OK, perhaps I am missing something obvious here, but this little test left me a bit confused:
Code:
testlabel.testing:
namespace .
        jmp testing._done
_done:
        retn
end namespace    

I would have assumed that the jump would refer to "testlabel.testing.testing._done", but fasmg treats it as if it is about to jump to ""testlabel.testing._done". Of course, fasmg also accepts "jmp _done". If I change "testing" in the jump to "lala", the compiler will complain about not recognising ""testlabel.testing.lala._done". As expected of course, but why is it OK with "testing._done"?

When looking for a namespace, fasmg always searches for a defined symbol. In this case, when it looks for "testing" namespace, it first looks for "testlabel.testing.testing", but there is no such symbol defined, so it continues search in the parent namespace, finding "testlabel.testing". Only if it did not find any defined symbol at all, it would fall back to the symbol in current namespace.
