Hi,

Idiocy on my part, no doubt ... the intention is that the following simplistic demo script should output "Success" when run on perl 5.8.x, and output "Ok" when run on perl 5.00505: 
use strict;

my $var = '';

if($] > 5.007) {
  if(open (my $mem, '>', \$var)) {print "Success\n"}
}
else {print "Ok\n"}

It does as desired on perl 5.8.x, but fails to compile on 5.00505 (because there are too many arguments being supplied to open).

I gather the best solution has something to do with string eval ... which I've never used (to any great effect, anyway). And the 'eval' documentation didn't produce any "Aaaaah, I see" moments for me. (Changing the open call to a 2 argument form is not a viable solution :-)

Cheers,
Rob
