29253  61 

62 
 In locale expressions, instantiation replaces renaming. Parameters 

63 
must be declared in a for clause. To aid compatibility with previous 

64 
parameter inheritance, in locale declarations, parameters that are not 

65 
'touched' (instantiation position "_" or omitted) are implicitly added 

66 
with their syntax at the beginning of the for clause. 

67 

68 
 Syntax from abbreviations and definitions in locales is available in 

69 
locale expressions and context elements. The latter is particularly 

70 
useful in locale declarations.

73 
expressions. Qualifiers (prefixes) may be specified in locale

790 
* Outer syntax: string tokens may contain arbitrary character codes 

791 
specified via 3 decimal digits (as in SML). E.g. "foo\095bar" for 

792

799 

26681  800 
* Unused theorems can be found using the new command 'unused_thms'. 
801 
There are three ways of invoking it: 

802 

803 
(1) unused_thms 

804 
Only finds unused theorems in the current theory. 

805 

806 
(2) unused_thms thy_1 ... thy_n  

807 
Finds unused theorems in the current theory and all of its ancestors, 

808 
excluding the theories thy_1 ... thy_n and all of their ancestors. 

809 

810 
(3) unused_thms thy_1 ... thy_n  thy'_1 ... thy'_m 

811 
Finds unused theorems in the theories thy'_1 ... thy'_m and all of 

812 
their ancestors, excluding the theories thy_1 ... thy_n and all of 

813 
their ancestors. 

814 

26718  815 
In order to increase the readability of the list produced by 
816 
unused_thms, theorems that have been created by a particular instance 

26874  817 
of a theory command such as 'inductive' or 'function' are considered 
818 
to belong to the same "group", meaning that if at least one theorem in 

26718  819 
this group is used, the other theorems in the same group are no longer 
820 
reported as unused. Moreover, if all theorems in the group are 

821 
unused, only one theorem in the group is displayed. 

822 

823 
Note that proof objects have to be switched on in order for 

824 
unused_thms to work properly (i.e. !proofs must be >= 1, which is 

26874  825 
usually the case when using Proof General with the default settings). 
26681  826 

26650  827 
* Authentic naming of facts disallows adhoc overwriting of previous 
828 
theorems within the same name space. INCOMPATIBILITY, need to remove 

829 
duplicate fact bindings, or even accidental fact duplications. Note 

830 
that tools may maintain dynamically scoped facts systematically, using 

831 
PureThy.add_thms_dynamic. 

832 

26660  833 
* Command 'hide' now allows to hide from "fact" name space as well.

* Method "induct_scheme" derives userspecified induction rules 
27067  911 
from wellfounded induction and completeness of patterns. This factors 
912

* More flexible generation of measure functions for termination 

917 
proofs: Measure functions can be declared by proving a rule of the 

918 
form "is_measure f" and giving it the [measure_function] attribute. 

919 
The "is_measure" predicate is logically meaningless (always true), and 

920 
just guides the heuristic. To find suitable measure functions, the 

921 
termination prover sets up the goal "is_measure ?f" of the appropriate 

922 
type and generates all solutions by prologstyle backwards proof using 

923 
the declared rules. 

924 

925 
This setup also deals with rules like 

926 

927 
"is_measure f ==> is_measure (list_size f)" 

928 

929 
which accommodates nested datatypes that recurse through lists. 

930 
Similar rules are predeclared for products and option types.

theorems within a class context produce both relative results (with 

1294 
implicit parameters according to the locale context), and polymorphic 

1295 
constants with qualified polymorphism (according to the class 

1296 
context). Within the body context of a 'class' target, a separate 

1297 
syntax layer ("user space type system") takes care of converting 

1298 
between global polymorphic consts and internal locale representation.

* Overloaded definitions are now actually checked for acyclic

INCOMPATIBILITY, use ``defs (unchecked overloaded)'' to admit more

1364 
Polymorphic constants are represented via type arguments, i.e. the 

1365 
instantiation that matches an instance against the most general 

1366 
declaration given in the signature. For example, with the declaration 

1367 
c :: 'a => 'a => 'a, an instance c :: nat => nat => nat is represented 

1368 
as c(nat). Overloading is essentially simultaneous structural 

1369 
recursion over such type arguments. Incomplete specification patterns 

19714  1370 
impose global constraints on all occurrences, e.g. c('a * 'a) on the 
19715  1371 
LHS means that more general c('a * 'b) will be disallowed on any RHS.
