What's with structures? I would like to see them in Euphoria someday.
Language is good if code explains itself (if no comments needed).

structure COLOR
    integer red
    integer green
    integer blue
end structure

COLOR color
color.red = 255
color.green = 0
color.blue = 0

? color.red
? color.blue
? color.green

---
In current version of Euphoria, closest I can get to structures is like
this:

constant COLOR_RED = 1
constant COLOR_GREEN = 2
constant COLOR_BLUE = 3

-- Here I describe my structure:
-- 1. integer red
-- 2. integer green
-- 3. integer blue
type COLOR (sequence s)
    if length (s) != 3 then
        return false
    end if
    if not integer (s [COLOR_RED]) then
        return false
    end if
    if not integer (s [COLOR_GREEN]) then
        return false
    end if
    if not integer (s [COLOR_BLUE]) then
        return false
    end if
    return true
end type

COLOR color
color = {255, 0, 0}
? color [COLOR_RED]
? color [COLOR_GREEN]
? color [COLOR_BLUE]
