Lua is a dynamic language - new global functions and variables can be
defined (and undefined) at any time. Because of this, there is no
reasonable way for lua_load to know for sure whether a function will
actually exist at a certain point in a script without running it to
that point first. I realise this might seem unfortunate, but it is the
nature of the thing. This is kind of the downside of so

I think that returning dummy values in a dry run.
