For those who are curious, PEU started with the sequence engine *first*,
and then the byte-code interpreter (actually just a loop calling a
function pointer) and then came the parsing of actual source code. Having
sequences at first helped during development, because I could code in C
with Euphoria-style thought processes.
David Cuny started his Gnuphoria with the parser first, and had his
sequence engine designed separately to be merged in later.
Another thing that might be of interest to the OS folk, is that it might
not be too difficult to add multi-threading capability to PEU. The
interpreter could easily switch between which set of bytecodes to execute
at any given time. How to start another thread is the question... (from
an .ex file most likely) and whether or not each thread shares the same
global variables... things could get messy.
And if I can ever get PEU to compile and run with WATCOM, Hawke can
compile with all the optimization settings he pleases. Open source is so
cool... to bad the Portable part of PEU isn't up to par, presently it is
pretty poopy. Work on fixing that should start soon.

I got to thinking that assigning to an object would be the most efficient
way to ignore a result. This is what I've used most often anyway.
object junk
junk = graphics_mode(-1)
But when I'm too lazy to declare of variable for a quick value I need to
use later, I've been known to do something like:
junk = complex_calculation()
junk = junk + 0 * wait_key()
junk = junk + graphics_mode(-1)
? junk
I need a write-only variable so I'm not tempted to do this... or a place
where I can put my junk and not be able to dig through it later. Of
course, if I had good programming habits, none of this would be a problem.
