Could you consider that the word "commonly" means sometimes opposed things for
different people?

I suggest spinning the DOS graphic functions off to a separate include file,
which does not need to be standard. They are specialised - much more than set
operations -, and in 6 or 7 years I never used any of them a single time. This
will make Euphoria simpler.
