Debug Block?

I was looking through the feature requests on the SF.net page trying to clean
things up. A lot of old suggestions exist, some of which were already
implemented, so I closed them.  Anyway, I ran across a feature request by CK
Lester and figured I would bring his suggestion to the forum for discussion so we
can either implement (do not think it would be hard) or clear the suggestion. No
reason to have it sit there in limbo for no reason. Keep in mind, I am just
brining this to peoples attention. It's not my idea, although, I think it's a
good one.

http://sourceforge.net/tracker/index.php?func=detail&aid=1771686&group_id=182827&atid=902785

He is basically suggesting the ability to remove debug code in the final copies
of your Euphoria source. His suggestion is instead of:

--- code
if DEBUG then
    printf(1, "Loop var is %d\n", {loopVar})
end if
--- code

which would be included in your final code, therefore causing extra processing
for no reason (has to check DEBUG condition). His idea is that a debug statement
be added:

with debug

--- code
. printf(1, "Loop var is %d\n", {loopVar})
--- code

His suggestion was any line starting with a . would be debug code. Thus, when
with debug or without debug is in the source code, the lines starting with .
would not even be emitted to the final versions of your Euphoria programmer,
thus, debug code would cause no slow down in your final version of your app.

I also thought possibly instead of . you could:

with debug

debug
    printf(1, "Loop var is %d\n", {loopVar})
    -- more debug code
end debug

Over all I do not see any bad side effects, only benefits, but wanted to get
your input. I do think a more defined block, such as debug ... end debug would
make the source code a bit cleaner and more easily understood, but everyone can
go read CK's feature request on the SF URL listed above.
