Re: Variable behaving as a function call

If you are on Perl 5.16 or above, you can take references to most built-in functions, using the syntax: \&CORE::builtin.

If you are on an earlier version, that isn't allowed, so you'd need to use wrappers:

$b = 0; 
$x = $b ? sub{  gmtime( @_ ) } : sub{ localtime( @_ ); }; 
print $x->( 123456 );;
1 0 0 1 0 70 4 0 0

$b = 1; 
$x = $b ? sub{  gmtime( @_ ) } : sub{ localtime( @_ ); }; 
print $x->( 123456 );;
1 0 0 1 0 70 4 0 0

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.

You need to replace `@_` with `$_[0]` because the argument is evaluated in scalar context.	[reply] [d/l] [select]
