I'm with Arne on this one. I expect programmers using a language to at
least thoroughly understand the datatypes for a language. Granted,
leading zeros are a pretty crappy prefix choice, which is why a lot of
languages use something else, but a diligent _learning_programmer should
have discovered this crappy choice when reading about literals.
