As has been noticed before, things like `as` would end up causing something like `assert` to be parsed as `as sert`, and thus needed explicit workarounds like f7c22d7 (for `as`, `is` and `has`), or 4a9d96c (for `box`). #6 also is an issue of this kind (for `mut`). Basically, we were fixing this issue as we hit it each time, in an ad-hoc way at the _use site_ of the specific problematic prefix. This PR fixes it once and for all, by making all the strings make sure that they aren't a prefix of a longer string (by using a negative lookahead), that way the use-sites don't need to worry about these strings. Thus, this PR also cleans up the previous workarounds that were added in the past.
