tuned;

present type variables; tuned;

unparse: more accurate markup for syntax consts, notably binders;

notation: proper markup for type constructor / constant;

tuned signature;

CONST syntax with positions;

moved CONST syntax/translations to their proper place;

renamed sprop "prop#" to "prop'" -- proper identifier; eliminated spurious symbolic string bindings (logic, any etc.); hardwired special "prop" vs. "prop'" conversion; tuned;

merged

raised timeout further, for SML/NJ
