Subject: Defining variables - optionally required.

Hi all,

Forgive the suggestion if it has been done to death before I joined in.
I would like some facility to change the behaviour so that variables
have to be declared before use. It would catch many of (my) typos.

VB has set declare. I always use it if I can when forced to use that
language.

I recognise that it would have to be set on a per module or per class
basis, if for no better reason than the existing libraries would
otherwise be broken. The state of this switch would have to be
maintained in the class or module record for testing at run time.

It is therefore a language issue for Rite, not a flag for the
interpreter.

Two ideas.....

Class Sample < Object  declare
   var @foo
   var @bar
   def bodgit()
       @oops = "Error"       #  error @oops not declared
   end
end

Class Sample
   #pragma declare
   var @foo
     etc

Comments. Ways to get the same effect now?

Regards

Ian
