${"FOO"} a symbolic reference, and that's at compile-time that perl barfs.
(in Perl_mod() - op.c)
BTW ( of symbolic refs) , I stumbled on this when fixing the
braces & interpolation problem:
$ perl -le 'my $b=1; $a = "b"; print $$a'
$
leaving the 'my' out gets the expected behaviour.
I rarely used symbolic references in Perl - Is this a bug or a feature ?
