coroutines working with HsLua were unsuccessful. No coroutine related
functions are exported from the default module for that reason. Pull
requests intended to fix this are very welcome.

-- **Why are there no predefined stack instances for default numerical types?**
- HsLua defines instances for the `Peekable` and `Pushable` type-classes
- only if the following law holds: `return x == push x *> peek x`. Lua can be
- configured during compilation to use longer or shorter number types, e.g. by
- setting the 32-bits flag. This makes it impossible to verify the correctness
- of the above equation for any fixed numeric Haskell type.
-
- Instances for numerical types can be based on those of LuaInteger and
- LuaNumber and are easy to write. Therefore, hslua doesn't provide any such
- instances.
