X_GEN_TAC : (term -> tactic)

- STRUCTURE
- SYNOPSIS
- Specializes a goal with the given variable.
- DESCRIPTION
- When applied to a term x', which should be a variable, and a goal A ?- !x. t, the tactic X_GEN_TAC returns the goal A ?- t[x'/x].
A ?- !x. t ============== X_GEN_TAC "x'" A ?- t[x'/x]

- FAILURE
- Fails unless the goal’s conclusion is universally quantified and the term a variable of the appropriate type. It also fails if the variable given is free in either the assumptions or (initial) conclusion of the goal.
