This is what Mr. Pelc remarked, regarding such style
of programming - yes, many years ago I was guilty of
that too - already 15 years ago:

"Although the code is compilable and can be made efficient,

Maybe he changed his mind since that time - well, since
he's here, you may want to ask him a question.

I take the last paragraph as a sort of passive-aggressive asking
of some indirectly
asked question. Hence I don't really know what your/the question
is. Never mind,
you opened the box.

Of course I change my mind in 15 years. I'm a human being and so
am entitled to
do so and will do so.

Working code beats all. Clear maintainable code that is easy to
understand is
best. I am stil maintaining 40 year old code and my brain is not
as fast as it used
to be. Keep it simple. Poking around in a Forth source tree of 1.4
million lines
of source code is not what I want to do.

Once twp implementation techniques provide performance within
(say) a factor of
1.5 or 2 of each other, I stop worrying. Short words are better
than long ones.

The locals or Forth stack discussions between Anton and myself
show up a design
flaw I made 30 years or more ago when the VFX native code
generator was new.
The use of ADDR <local> to return the address of the local is a
mistake that can
be replaced by a LOCAL[ size ] buffer. When this is done, code
generation of
locals can become significantly better. However, I'm not going to
wreck client
code for it. My successors can argue about it.

On Usenet, I take people who use their real names more seriously
than those who
do not. Just get a better flame-proof suit and stop being so
precious.
