I'm sorry, but a language for which a fully-compliant compiler takes a decade to write is horribly broken. (Computer) languages should not inspire "puzzle books". Too often I'll see colleagues scratching their heads wondering why a piece of code works a certain way, or why something doesn't work the way it's supposed to. Languages are a tool to get things done. The more time you spend lost in the entrails of a language, the more you're wasting your time.
