for i,v in globals() do ... end

This is a FAQ. In Lua 4.0 you need wrap the code inside
	"return function ()... end"
and then run dostring on the wrapped code. If dostring succeeds, then there
was no syntax error and you get the code as a return value that you can run
simply by calling it with (). If there are syntax errors, then dostring 
returns nil and an error messages.

In Lua 5.0, you can use loadstring without having to wrap your code. The
rest is the same.

What are "associated member variables"?
