Strings

Sometimes the cost of representing strings as lists of Char can be too much. In this case, you can instead use packed strings. There are a number of options:

* The standard Data.PackedString type
* One of the newer packed string libraries, for example FastPackedString
* Unboxed arrays of Word8 or Char
* Ptrs to foreign malloced Word8 buffers

The packed string libraries have the benefit over arrays of Word8 or Char types, in that the provide the usual list-like operations.
