As much as I hate 'as' and try to avoid it, it also covers several things that are impossible otherwise (integer <-> float casts are impossible without it, e.g.). I've found that sometimes just being able to express a coerce-to-type-damn-the-consequences is useful. Another painful bugbear is when I'm converting to/from usize and I know that it is really either going to be a u64 or maybe u32 in a few cases, and I don't care about breaking usize=u128 or usize=u16 code. Give me a way to say that u32 is Into<usize> for my code!
