\TYPE {GENL : (term list -> thm -> thm)}
\SYNOPSIS
Generalizes zero or more variables in the conclusion of a theorem.
\KEYWORDS
rule, quantifier, universal.
\DESCRIBE
When applied to a term list {[x1;...;xn]} and a theorem {A |- t}, the inference
rule {GENL} returns the theorem {A |- !x1...xn. t}, provided none of the
variables {xi} are free in any of the assumptions. It is not necessary that
any or all of the {xi} should be free in {t}.
{
A |- t
------------------ GENL "[x1;...;xn]" [where no xi is free in A]
A |- !x1...xn. t
}
\FAILURE
Fails unless all the terms in the list are variables, none of which are
free in the assumption list.
