30955  15 
* Class semiring_div requires superclass no_zero_divisors and proof of div_mult_mult1; 
30930  16 
theorems div_mult_mult1, div_mult_mult2, div_mult_mult1_if, div_mult_mult1 and 
17 
div_mult_mult2 have been generalized to class semiring_div, subsuming former 

18 
theorems zdiv_zmult_zmult1, zdiv_zmult_zmult1_if, zdiv_zmult_zmult1 and zdiv_zmult_zmult2. 

19 
div_mult_mult1 is now [simp] by default. INCOMPATIBILITY.

30955  21 
* Power operations on relations and functions are now dedicated constants: 
22 

23 
relpow with infix syntax "^^" 

24 
funpow with infix syntax "^o" 

25 

30964  26 
Power operations on algebraic structures retains syntax "^" and is now defined 
27 
generic in class recpower; class power disappeared. INCOMPATIBILITY. 

28 

29 
* ML antiquotation @{code_datatype} inserts definition of a datatype generated 

30 
by the code generator; see Predicate.thy for an example.

Tutorial on Locales ("locales" manual) for details. 
29253  89 

90 
 In locale expressions, instantiation replaces renaming. Parameters 

91 
must be declared in a for clause. To aid compatibility with previous 

92 
parameter inheritance, in locale declarations, parameters that are not 

93 
'touched' (instantiation position "_" or omitted) are implicitly added 

94 
with their syntax at the beginning of the for clause. 

95 

96 
 Syntax from abbreviations and definitions in locales is available in 

97 
locale expressions and context elements. The latter is particularly 

98 
useful in locale declarations. 

99 

100 
 More flexible mechanisms to qualify names generated by locale 

101 
expressions. Qualifiers (prefixes) may be specified in locale

673 
"close Gamma T1". We are looking for other examples where this 

674

875

876 

26718  877 
In order to increase the readability of the list produced by 
878 
unused_thms, theorems that have been created by a particular instance 

26874  879 
of a theory command such as 'inductive' or 'function' are considered 
880 
to belong to the same "group", meaning that if at least one theorem in 

26718  881 
this group is used, the other theorems in the same group are no longer 
882 
reported as unused. Moreover, if all theorems in the group are 

883 
unused, only one theorem in the group is displayed. 

884 

885 
Note that proof objects have to be switched on in order for 

886 
unused_thms to work properly (i.e. !proofs must be >= 1, which is 

26874  887 
usually the case when using Proof General with the default settings).

* Method "induct_scheme" derives userspecified induction rules

974

* More flexible generation of measure functions for termination 

979 
proofs: Measure functions can be declared by proving a rule of the 

980 
form "is_measure f" and giving it the [measure_function] attribute. 

981 
The "is_measure" predicate is logically meaningless (always true), and 

982 
just guides the heuristic. To find suitable measure functions, the 

983 
termination prover sets up the goal "is_measure ?f" of the appropriate 

984 
type and generates all solutions by prologstyle backwards proof using 

985 
the declared rules. 

986 

987 
This setup also deals with rules like 

988 

989 
"is_measure f ==> is_measure (list_size f)" 

990 

991 
which accommodates nested datatypes that recurse through lists. 

992 
Similar rules are predeclared for products and option types.

theorems within a class context produce both relative results (with 

1356 
implicit parameters according to the locale context), and polymorphic 

1357 
constants with qualified polymorphism (according to the class 

1358 
context). Within the body context of a 'class' target, a separate 

1359 
syntax layer ("user space type system") takes care of converting 

1360 
between global polymorphic consts and internal locale representation.
