in reply to Changing a number to a string

It could also have something to do with the way you initialize it. 
# initializing like this will represent '0' as a number
$foo = 0;

# by double quoting it, the '0' should be seen as a string
$foo = "0";

    How would you know if it's being seen as a string or a number, though? Because once you try to test that, Perl will just Do The Right Thing anyway.

    $foo = 0; # Declaring as a number
if ($foo eq '0') {
    print "Oops, it's a string!\n";
}

$foo = "0"; # Declaring as a string
if ($foo == 0) {
    print "Oops, now it's a number!\n";
}

    Bottom line: Perl will always Do The Right Thing when it comes to worrying about stringifying numbers or number-fying strings.

      FYI, I think the "standard" hack for seeing if a scalar has been used in a string context is ^, but it isn't a very good hack.

      I mean to write a module that exposes what types of values a scalar already has cached as well as nifty calls like looks_like_number().
