Subject: RE: comparing symbols coming from gensym?

Message-ID: <DNEMKBNJBGPAOPIJOOICIEAOCMAA.drew.adams@oracle.com> (raw)
In-Reply-To: <E1E7nDq-0002ci-00@lab1.ma.utexas.edu>
Why is it that
(setq a (gensym)) ;=> G2007
a ;=> G2007
(equal a 'G2007) ;=> nil
while
(setq a 'foo) ;=> foo
a ;=> foo
(equal a 'foo) ;=> t
Perhaps because gensym, like make-symbol, doesn't intern the symbol it
creates? The reader interns `foo' in (setq a 'foo). So, they are different
symbols: one is interned in obarray; the other is an uninterned symbol.
