1. Re: type string
Well, from my benchmarking, this is an OK type, although with longer =
strings it does rise to 3rd place--behind Jeff's string6 (with Mike's =
modification) at 2nd place, and Gabriel's string12 in 1st.
Christopher, are you using Daniel's benchmark program? I haven't used =
that yet, I think it might help if I started though...
BTW - Gabriel, I'm impressed by your string type, but... what made you =
think to redefine the parameter? I didn't even know that that was =
possible in Euphoria (and I'm not sure I like it, although in this case =
a definite speed benefit is there.)

Hi,
I couldn't resist jumping in on an optimization race:)
This one runs a bit faster in my tests, especially for
longer sequences.
-----------------------------------------------
global type string13(object x)
if atom(x) then
return 0
end if
-- ensure all elements are in the range 0 to 255
if compare(x, and_bits(255, x)) then
return 0
end if
-- ensure there's no sub-sequences
for i =3D 1 to length(x) do
if not integer(x[i]) then
return 0
end if
end for
return 1
end type
-----------------------------------------------
Have fun,
Christopher D. Hickman
