so I was testing some stuff I want to do in a large project.. I wanted my configuration files to contain perl's regeular expressions to allow the configs to be as flexible as possible.. so I threw together a nasty little test script (doesn't use strict or do any error checking) but basically proves that it can work and that its just pretty damn cool :)
test.pl 
#!/usr/bin/perl

open(R, "file.r");
while(<R>) {
        chomp;
        push @REG,$_;
}

open(I, "file.i");
while(<I>) {
        chomp;
        foreach $regex (@REG) {
                if(/$regex/) {
                        print "$_ matched $regex\n";
                        for $i (1..5) {
                                if($$i) {
                                        print "\t\$$i: $$i\n";
                                }
                                else { last; }
                        }
                }
        }
}

Perhaps I'm a just easy to impress, but does anyone else see the beauty and power of this? :)
its those little revelations that make life more fun :)
anyone else have any "little things" that have made their life infinitely more fun?
