17 subsection \<open>Notes on Isac's programming language\<close>
19 Isac's programming language combines tacticals (TRY, etc) and
20 tactics (Rewrite, etc) with list processing.
22 In order to distinguish list expressions of the meta (programming)
23 language from the object language in Lucas-Interpretation, a
24 new 'type xlist' is introduced.
25 TODO: Switch the role of 'xlist' and 'list' (the former only used
28 Isac's programming language preceeded the function package
29 in 2002. For naming "axiomatization" is used for reasons of uniformity
30 with the other replacements for "axioms".
31 Another reminiscence from Isabelle2002 are Isac-specific numerals,
32 introduced in order to have floating point numerals at a time,
33 when Isabelle did not consider that requirement. For the sake of uniformity
34 'nat' from List.thy is replaced by 'real' by 'fun parse',
35 however, 'fun parseNEW' has started to replace this fix (after finishing
36 this fix, there will be a 'rename all parseNEW --> parse).
38 Note: *one* "axiomatization" over all equations caused strange "'a list list"

62 (1) revise, if definition of identifiers like LENGTH_NIL are still required.
63 (2) switch the role of 'xlist' and 'list' in the functions below, in particular for
64 'foldr', 'foldr_Nil', 'foldr_Cons' and 'xfoldr', 'xfoldr_Nil', 'xfoldr_Cons'.
65 For transition phase just outcomment InsSort.thy and inssort.sml.
