    Works with strict and doesn't require an eval() 
    sub foo {
    print "in foo()\n";
}
my $func_name = "foo";
&{\&{$func_name}}();

__output__

in foo()

      Cute. Is this a Perl bug?

      Either way a simple no strict 'refs'; seems like the way to go. 

      sub foo { print "in foo\n"; }

{
  no strict 'refs';
  &{"foo"};
}

        Nope, this is perfectly legal. It just creates a reference, which is then dereferenced and since it's a normal reference (see. not symbolic) strict doesn't have a problem with it. I originally saw this funky trick in a node by gbarr.
