Re: Check for sub / don't fail on non-existent sub

[SFLEX]

I use this:

my $sub_x = 'Some::Sub';
my $Result = 'Bad';
if (exists &{$sub_x}
        && (ref $sub_x eq 'CODE' || ref $sub_x eq '')) {
        $Result = 'Good';
    }
print $Result . "\n"

Simpler:

my $sub_x = 'Some::Sub';
if (defined(&$sub_x)) {
    print("It's there\n");
} else {
    print("It's not there\n");
}

Wow, I expected that defined() would be applyed to the result of $sub_x, but a test showed that it doesn't.
Thank you all!
