in reply to Strict, strings and subroutines

Others have given you several solutions, but there is one more. strict will only cause an error if you try to call the sub by using a string. It does not stop you taking a reference. So

my $sub = \&{'do_'.$type}; $sub->();

Is perfectly legal. But if you don't want the extra variable

(\&{'do_'.$type})->();

will work too. But the benefit of using the variable is that you can check that the sub actually exists with

my $sub = \&{'do_'.$type}; die "Unknown sub 'do_$type'" unless defined(&$sub);
