`my $coderef = \&hiya;` is far more conventional, but both are ok for subroutines. Neither will work for operators such as `gmtime` and `localtime`, though. Since 5.16: `my $time_zone_func = $file =~ /^London/ ? \&CORE::gmtime : \&CORE::localtime; strftime($date_format, $time_zone_func->(time))` [download] Backwards compatible: `my $time_zone_func = $file =~ /^London/ ? sub { gmtime($_[0]) } : sub { localtime($_[0]) }; strftime($date_format, $time_zone_func->(time))` [download] or `my $time_zone_func = sub { $file =~ /^London/ ? gmtime($_[0]) : localtime($_[0]) }; strftime($date_format, $time_zone_func->(time))` [download]	[reply] [d/l] [select]
