\TYPE {aconv : (term -> term -> bool)}

\SYNOPSIS
Tests for alpha-convertibility of terms.

\KEYWORDS
alpha.

\DESCRIBE
When applied to two terms, {aconv} returns {true} if they are
alpha-convertible, and {false} otherwise.

\FAILURE
Never fails.

\EXAMPLE
A simple case of alpha-convertibility is the renaming of a single quantified
variable:
{
   #aconv "?x. x=T" "?y. y=T";;
   true : bool
}
\SEEALSO
ALPHA, ALPHA_CONV.
