In Lua, writing "function foo() ... end" is really a shortcut for "foo
= function() ... end". Just like any other variable assignment, that
won't do anything until the statement actually gets executed.

Why do you not want to execute the file, but you want to load (and
presumably execute) the functions defined in it? Perhaps you want to
look at sandboxing.
