Wow! Thanks! This is pretty much exactly what i'm thinking of with some minor modification (i wish my program was about Unicorns called Twilight Sparkle!!
I'm having trouble following your subs "name", "colour" etc though.
Could you explain those? I'm guessing that if i attempt to get the value of "name" before i've assigned it a value, it'll call the _build_X sub and so return a default value. But i'm not entirely sure how it does it? Also i've never seen the "//=" operator before.
Thanks!
