ARRGGGHH! It is *not* a bug. It is an improvement. It can actually help
people write better code.

I believe you spelled the colloquial word for copulation incorrectly, it
is not spelled 'fixed'

What 'bug'? You have actually got it right, now.

You need to fix these then so that they can be just as helpful as the 
interpreter.

That's just one point of view. Other points of view are just as valid but
you prevent your customers from having the freedom of choice. You just
impose your view on us.

This I can now believe. I suspect you are not joking.

There are no reasons - just opinions. Please justify why
the absence of forward referencing for routines is a good thing. 

And there are other messages in EUForum for supporting other valid 
points of view too.


I'm begging...please don't destroy this good thing. Please.


BTW, Robert, are you ignoring me? Messages and emails that I've sent to
you continue to go unanswered.
