Re: [CFD] Local functions for Lua 4.1

Sorry, my last post wont solve the problem, but it will point out that there
is a problem!

Do you mean "holy" debate? :-)  I'm not smirking at you, I think its a
Freudian misspelling! The argument did rage for a while and was difficult to
follow but I think people learnt a lot from it. I think are a few little
nagging details of the scoping issue which could probably do with being
addressed and this is one of them.

Riki:
>> I would also argue for the syntactic inclusion of
global v = 7
and
global function g(args) body

You may be able to do this with the global keyword already (untested) eg.
function foo()
  global v
  v = 7
end

just like:
function foo()
  local v
  v = 7
end

I think the global keyword only turns on testing of globals and doesnt allow
you to create them from with another scope (although Python does allow you to
do this).

>> There are already so much changes in the 4.1 snapshots that _I_
would call the final version 5.0.

I think I agree. 3.2 to 4.0 introduced major API changes. 4.0 to 4.1
introduces major syntax changes. I think calling it version 5.0 better
reflects the amount of discussion and effort that has gone into the version
change.
