It's threads like this that most of us (IMO/AFAICT) on this list thrive
on. It's what keeps me here anyway. It trancends whatever platform you're
developing on, and almost becomes a lesson in general algorithmics, rather
than good old Euphoria.

It's not possible to write down all possible speed up tricks. It might be
possible to come up with general ideas on how to do something, and how to
optimise them. But to write everything down? :)
e.g. if condition1 or condition2 then
-- something
else
-- womble
end if
becomes:
if condition1 then -- something
elsif condition2 then -- same something
else -- womble
endif
You'll find that in most cases code optimised for speed is exponentially
larger then code optimised for space.
After all, I'm the one around here who likes finding "pure" Euphoria ways
of doing things, just like in the abs() wars, and my solutions tend to be
fairly near the mark for being the slowest example available :)

PS Minor niggle. There are one or two folks who don't have forced
linebreaks every 74 characters or so in their mails. This isn't really
a bad thing, but it makes it a bit of a hassle to reply to your
messages.
For instance, to reply to this message I had to physically insert CRLFs
and ']'s into the text I quoted from the original, because there were
no linebreaks in each paragraph.
Don't get me wrong, I'm not intentionally picking on anyone, it just
bugs me sometimes... :( :)
