Just wondering... Isn't there a way of specifying the data type without 
using a string lookup? Something like this:

tolua_pushusertype(L, pFoo, tolua_type_Foo);

Where tolua_type_Foo is a special type structure defined somewhere by 
tolua? This will save a possibly heavy (hash)map lookup for compile-time 
known types.

Cheers,
Andrea.
