Hello Mitar,

 I would like to call it like create (Axon undefined) (AxonAny

 result. If I would call it like create (AxonAny undefined) (AxonAny
 undefined) I would get Nerve (AxonAny a) (AxonAny b) as a result.
 And so on.

look into HsLua sources. it does something like you asking (converting
return type into sequence of commands) so it mau be what you are
looking for. it uses typeclasses for this effect. the same technique
used in haskell printf implementation afaik

While reading the source code I found that in loadstring you do not
make sure that free is called even in a case of an exception. Is this
not necessary?
