Portability : non-portable (depends on GHC)

Core Lua API. This module provides thin wrappers around the respective
functions of the Lua C API. C functions which can throw an error are
wrapped such that the error is converted into an @'Exception'@. However,
memory allocation errors are not caught and will cause the host program
to terminate.
