ERRATA FOR ISABELLE MANUAL** THM : BASIC INFERENCE **Pure/tactic/lift_inst_rule: now checks for distinct parameters (could alsocompare with free variable names, though). Variables in the insts are nowlifted over all parameters; their index is also increased. Type vars inthe lhs variables are also increased by maxidx+1; this is essential for HOLexamples to work.** THEORY MATTERS (GENERAL) **Definitions: users must ensure that the left-hand side is nothingmore complex than a function application -- never using fancy syntax.
