corrected slip

tuned
2012-01-07, by haftmann
restore convenient code_abbrev declarations (particulary important if List.set is not the formal constructor for sets)
2012-01-07, by haftmann
moved lemmas about List.set and set operations to List theory

2012-01-06, by wenzelm
farewell to theory More_List
2012-01-06, by haftmann
dropped unused nth_map
2012-01-06, by haftmann
more explicit NEWS
2012-01-06, by haftmann
refined case syntax again, improved treatment of constructors without arguments, e.g. "case a of (True, x) => x";
2012-01-06, by wenzelm
tuned;
2012-01-06, by wenzelm
improved list comprehension syntax: more careful treatment of position constraints, which enables PIDE markup;
2012-01-06, by wenzelm
tuned -- more direct @{type_name set} (NB: binder_tr' retains the original non-syntax type for the bound/free variable);
2012-01-06, by wenzelm
recovered case syntax for of_int, also with source positions (appears to be unused nonetheless);
2012-01-06, by wenzelm
more careful treatment of outermost constraints, e.g. constructors without arguments (despite loss of positions for catch-all variables);
2012-01-06, by wenzelm
proper refs;
2012-01-06, by wenzelm
incorporated canonical fold combinator on lists into body of List theory; refactored passages on List.fold(l/r)
