isabelle update -u control_cartouches;

empty -> Map.empty

more symbols;

standardized towards new-style formal comments: isabelle update_comments;

isabelle update_cartouches -c -t;

prefer symbols;

proper context for assume_tac (atac remains as fall-back without context);

modernized header;

folded 'Option.set' into BNF-generated 'set_option'

tuned proofs;

tuned white space;

eliminated obsolete "standard";

modernized specifications;

renamed lemmas: ext_iff -> fun_eq_iff, set_ext_iff -> set_eq_iff, set_ext -> set_eqI

expand_fun_eq -> ext_iff
expand_set_eq -> set_ext_iff
Naming in line now with multisets

modernized/unified some specifications;

cleanup type translations;

replaced a couple of constsdefs by definitions (also some old primrecs by modern ones)

modernized syntax declarations, and make them actually work with authentic syntax;

modernized syntax

Made Option a separate theory and renamed option_map to Option.map

re-eliminated Option.thy

replaced make_imp by rev_mp;

removed or modified some instances of [iff]

migrated theory headers to new format

Merged in license change from Isabelle2004

Replaced \<leadsto> by \<rightharpoonup>

*** empty log message ***

"Definite Assignment Analysis" included, with proof of correctness. Large adjustments of type safety proof and soundness proof of the axiomatic semantics were necessary. Completeness proof of the loop rule of the axiomatic semantic was altered. So the additional polymorphic variants of some rules could be removed.

Adapted to new simplifier.

Converted Fun to Isar style.
Moved Pi, funcset, restrict from Fun.thy to Library/FuncSet.thy.
Renamed constant "Fun.op o" to "Fun.comp"

Added unary and binary operations like (+,-,<, ...); Added smallstep semantics (no proofs about it yet).

Added check for field/method access to operational semantics and proved the acesses valid.
