2009-03-17 wenzelm 2009-03-17 strip_abss: always strip abstractions as far as possible, without keeping alternatives (which appear to be redundant anyway, but cause significant slowdown since discrimination nets collapse abstractions);

2009-03-05 wenzelm 2009-03-05 Consts.abbreviate: reject schematic term variables, prevent schematic type variables (hidden polymorphism) via Term.close_schematic_term -- see also 8f84a608883d;
2009-03-05 wenzelm 2009-03-05 eliminated Consts.eq_consts tuning -- this is built into tables and name spaces already;
