Symbol and Keyword types

[MichaelBurge]

It looks like Coalton doesn't have symbols or keywords as native types. They're very easy to add in a "custom Prelude", and they're even on the front page as an example(so I was surprised not to find them in the standard library), but you may want official CL compatibility types.

[stylewarning]

This is a good idea that's been tossed around a bit, a standard library package that just contains some common CL data types for compat, even if there aren't many built-in functions to manipulate them.
