UML is a big fail because of all the bloat and redundancy (20 different types to name the same thing) it brings in, when I learned some people actually want to create UML VM i was like O_o ... No human ever will be possible to maintain this pile of crap once it runs.

But alot of programmers use other cool code generators such as wizards or visual designers to create forms (or another stuff that has no impact on core of the program anyway).

Also think how the life would suck without (f)lex!
