Modules that have names that are also Go keywords don't work

[trotterdylan]

E.g. the struct module has to declare package struct at the top of the file, which is a compilation error. The obvious options seem to be:

1. Always prefix Grumpy package names so that there is never a keyword collision
2. Have special handling in grumpc that changes the way imports work for modules that are named the same as a Go keyword.

For hand-written codes that using grumpy will have less impact with 2, I guess.
struct is not ok, but copy is ok, so may be not so many there.
