      We can also do it in simple manner by using numeric operator for comparison without having regular expression used in the mentioned thread.

        I prefer the regular expression to numeric comparison, because...

        use strict; my $var = "xyz"; print "it's a single-digit number!!\n" if $var < 10;

        Is "xyz" really a single digit number?

        perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
