Re: checking bareword-filehandle

Is there a good reason not to use a lexical variable as file handle?

open my $FH, '>', 'whatever' or warn 'blah';

# much much later

if ($FH) { print $FH "something }
[download]

works for sure.

Evidently, but at the moment the open is in a different lexial scope as the print so I would need to declare a lexical $FH in the common enclosing scope - I'll do that eventually. But apart from your suggestions for suppressing the warning outright - is there really no easy way for checking such a handle?	[reply]

After skimming perlmod and perlref I've dug up `print FH $foo if *{$foo}{IO};` [download] which is somewhat ugly, but seems to work. Perl 6 - the future is here, just unevenly distributed	[reply] [d/l]
