dmd's spell checker only looks a distance of one, and uint64 is a distance of 
two from uint64_t. This is trivially changed, but I didn't do the longer 
distances because of the annoyances of false positives - variable name spelling 
doesn't work like english language spelling.

The issue is not, as has been suggested, that dmd doesn't do spelling checks on 
types.

There's really nothing "amazing" about a spell checker, it's just a better idea 
than not doing it.
