I would too. If I really want something to be global, I'll

It's not like I'm going to have 40 globals anyway, so this won't be
much writing.

To me there are still some problems regarding scoping with this,

if someboolean then
      global myvar = 0

print(myvar) -- Is this valid?
Why in the world would anyone do this? I can't think of any reason for a
global variable's existence to be conditional.

The "why" doesn't really matter, I think. The question is how
well-defined the behavior is (even if it's not necessarily useful) so
that a program has deterministic, understandable behavior in the face
of someone even accidentally doing something like this.

That's it exactly. The idea to make declaration of globals mandatory, is not to punish programmers but to help them finding errors. If the declaration of globals is ambigues, it wont really help the programmers at all.
