FOR THE LOVE OF GOD DO NOT WASTE YOUR LIFE ON SML!!! THERES A REASON WHY NOBODY USES IT! You'll bang your head against the utter inflexibility of the language again and again (die tuples, DIE!). And then there's the lack of semi decent quick reference documentation.

Either that or my instructor really knew how to torture people using SML and if you don't use in the retarded way he did then it might be a semi decent language.
