Re: When warnings get in the way

[salva]

for a one time construction I would use

if (defined $foo and $foo eq 'true') {...}

but if I needed to code similar tests in several places I would go for:

sub is_true ($) { defined $_[0] and $_[0] eq 'true' }

if (is_true $foo) {...}
if (is_true $bar) {...}
