Re: Modifying a Closure in 5.0 Alpha

["Peter Loveday" <peter@...>]

I can't seem to get this to work.  lua_pushupvalues() seems to return 0,
when called with the function I'm interested in on the top of the stack.

Is this the correct way to be using it, or am I doing something
fundamentally wrong?

Thanks!
