Agreed, I considered this. There are a couple of reasons why I didn't
propose a different keyword:
1. Rust tries hard to reuse keywords in general, since everyone likes a
small set of keywords.
2. I didn't really like any of the obvious options. The most obvious
keyword to switch to would be "inst" to mirror Haskell and so forth, but
is "impl"/"inst" really less confusing? I suspect many programmers would
want to "implement" a trait and would choose "impl".
