pushfunction

[Scott Parlane <scott@...>]

Hi,

I was wondering what problems, if any I will have with using the
attached patch ?

I call lua_pushfunction() with a value I previously got from
lua_topointer() from the same lua_State (but not in the same call, so
the function is no longer on the stack)

Regards,

Scott
