forward declaration of variables?

myfun (); if my fun is in another file. This is good.

But this doesnt work with variables or pseudo constants

If myvar was in another file and we use it here, just hope the other was compiled first.

the declaration myvar; produces a new local to the current file.

This is wrong.

it should work the same way. If a local is desired it should be declared as
local myvar;

So the upshot is if variables are to be shared between files they better all be declared in
a file that is compiled before everyone else or an endless stream of errors occurs.

It seems like ppl is uninventing well understood rules of scope.

Here's how I understand the scope:
