ASM_FOL_TAC : (string * thm) list * term -> goalstate
Fix up function arities for first-order proof search.
This function attempts to make the assumptions of a goal more `first-order'.
Functions that are not consistently used with the same arity, e.g. a function
f that is sometimes applied f(a) and sometimes used as an argument to other
functions, g(f), will be identified. Applications of the function will then
be modified by the introduction of the identity function I (which can be
thought of later as binary `function application') so that f(a) becomes
I f a. This gives a more natural formulation as a prelude to traditional
first-order proof search.
- FAILURE CONDITIONS
This function is not intended for general use, but is part of the initial
normalization in MESON and MESON_TAC.
