hyp_union : (thm list -> term list)

SYNOPSIS
Returns union of assumption lists of the given theorems.

DESCRIBE
When applied to a list of theorems, hyp_union returns the union (see union) of their assumption lists. Straight repetitions only arise if there were multiple instances of an assumption in a single assumption list. There is no elimination of alpha-equivalent pairs of assumptions, only ones which are actually equal.
   hyp_union [A1 |- t1; ... ; An |- tn] = A1 u...u An

FAILURE
