\TYPE {GSPEC : (thm -> thm)}
\SYNOPSIS
Specializes the conclusion of a theorem with unique variables.
\KEYWORDS
rule, genvars.
\DESCRIBE
When applied to a theorem {A |- !x1...xn. t}, where the number of universally
quantified variables may be zero, {GSPEC} returns {A |- t[g1/x1]...[gn/xn]},
where the {gi} are distinct variable names of the appropriate type, chosen by
{genvar}.
{
A |- !x1...xn. t
------------------------- GSPEC
A |- t[g1/x1]...[gn/xn]
}
\FAILURE
Never fails.
\USES
{GSPEC} is useful in writing derived inference rules which need to specialize
theorems while avoiding using any variables that may be present elsewhere.
