I have just begun using the Getopt::Long CPAN module, and I'm a bit confused about its return result. For example: 
use strict;
use warnings;
use Getopt::Long;
{
    my $blah;
    my $result = GetOptions('blah=i'    =>  \$blah);

    print "result = $result\n";
    print "blah = $blah\n";
}

By my understanding, blah is a required integer value, but when i invoke my script without a blah arg, i still get a true result:

perl -w getopt_test.pl
result = 1
Use of uninitialized value in concatenation (.) or string at getopt_test.pl line 12.
blah =

It makes sense that $blah is uninitialized, but i thought that $result would be false.

When i invoke this with a blah option, i get a true result also:

perl -w getopt_test.pl --blah 4
result = 1
blah = 4

As a side note:
By my understanding, i dont need to say --blah=4, i can say --blah 4, and that seems to parse correctly by my test runs.

So what am i missing here?
