Seems that your 'drawer' function is a member of your class. If so, you 
cannot use pushcfunction because it only allows non-member functions (or 
static ones) to be pushed.

You can take a look at Lunar itself. When it registers in Lua your class 
functions, it actually registers a function called 'thunk', which 
retrieves the member function to be called using upvalues.
