* Class semiring_div now requires no_zero_divisors and proof of div_mult_mult1; 

13 
theorems div_mult_mult1, div_mult_mult2, div_mult_mult1_if, div_mult_mult1 and 

14 
div_mult_mult2 have been generalized to class semiring_div, subsuming former 

15 
theorems zdiv_zmult_zmult1, zdiv_zmult_zmult1_if, zdiv_zmult_zmult1 and zdiv_zmult_zmult2.

Tutorial on Locales ("locales" manual) for details. 
29253  77 

78 
 In locale expressions, instantiation replaces renaming. Parameters 

79 
must be declared in a for clause. To aid compatibility with previous 

80 
parameter inheritance, in locale declarations, parameters that are not 

81 
'touched' (instantiation position "_" or omitted) are implicitly added 

82 
with their syntax at the beginning of the for clause. 

83 

84 
 Syntax from abbreviations and definitions in locales is available in 

85 
locale expressions and context elements. The latter is particularly 

86 
useful in locale declarations. 

87 

88 
 More flexible mechanisms to qualify names generated by locale 

89 
expressions. Qualifiers (prefixes) may be specified in locale

principles for inductive definitions. In contrast to 

650 
'nominal_inductive', which can only deal with a fixed number of

binders, it can deal with arbitrary expressions standing for sets of

atoms to be avoided. The only inductive definition we have at the

Gamma  Let x be t1 in t2 : T2

In this rule one wants to avoid all the binders that are introduced by 

661 
"close Gamma T1". We are looking for other examples where this 

662 
feature might be useful. Please let us know.

* Unused theorems can be found using the new command 'unused_thms'. 
851 
There are three ways of invoking it:

(1) unused_thms 

854 
Only finds unused theorems in the current theory. 

855 

856 
(2) unused_thms thy_1 ... thy_n  

857 
Finds unused theorems in the current theory and all of its ancestors, 

858 
excluding the theories thy_1 ... thy_n and all of their ancestors. 

859 

860 
(3) unused_thms thy_1 ... thy_n  thy'_1 ... thy'_m 

861 
Finds unused theorems in the theories thy'_1 ... thy'_m and all of 

862 
their ancestors, excluding the theories thy_1 ... thy_n and all of 

863 
their ancestors. 

864 

26718  865 
In order to increase the readability of the list produced by 
866 
unused_thms, theorems that have been created by a particular instance 

26874  867 
of a theory command such as 'inductive' or 'function' are considered 
868 
to belong to the same "group", meaning that if at least one theorem in

* Method "induct_scheme" derives userspecified induction rules

962

* More flexible generation of measure functions for termination 

967 
proofs: Measure functions can be declared by proving a rule of the 

968 
form "is_measure f" and giving it the [measure_function] attribute. 

969 
The "is_measure" predicate is logically meaningless (always true), and 

970 
just guides the heuristic. To find suitable measure functions, the 

971 
termination prover sets up the goal "is_measure ?f" of the appropriate 

972 
type and generates all solutions by prologstyle backwards proof using 

973 
the declared rules. 

974 

975 
This setup also deals with rules like 

976 

977 
"is_measure f ==> is_measure (list_size f)" 

978 

979 
which accommodates nested datatypes that recurse through lists. 

980 
Similar rules are predeclared for products and option types.

* The 'class' package offers a combination of axclass and locale to 
25129  1342 
achieve Haskelllike type classes in Isabelle. Definitions and 
1343 
theorems within a class context produce both relative results (with 

1344 
implicit parameters according to the locale context), and polymorphic 

1345 
constants with qualified polymorphism (according to the class 

1346 
context). Within the body context of a 'class' target, a separate 

1347 
syntax layer ("user space type system") takes care of converting 

1348 
between global polymorphic consts and internal locale representation.
