[DGD] Efficiency question.

[Keith Dunwoody]

If I call_other to a function that doesn't exist, nil
is returned, but no error occurs, correct?  How
efficient is this compared to calling a function with
an empty body?

For example, which is more efficient:

baz->foo();

or

baz->bar();

given that the function foo() is defined as

void foo() {

}

and bar has no definition.

Does this change if foo() had parameters and/or a
return value?

Thanks,
-- Keith
