Verbosity

I would like to directly use `primitive` arrays in a significant amount of code, and the verbosity of function names is very annoying.

I don't see a good reason why `newSmallArray` should be preferred to `new`. No other commonly used data structure library has this naming convention. Instead, the standard practice is to let library users disambiguate by qualified imports. The verbose naming scheme is perhaps justified at the level of `GHC.Prim`, but not here really.
