[sc-dev] ideas from ruby and clean

[ccos <ccos@xxxxxxxxxxxxxxxx>]

in ruby (1..4) gives a range much like sc's current array notation but 
you can also go

(1...4) giving [1,2,3]

unrelated, but more interesting, in clean language you can write [n..]:

which in sc could be written (n..) returning

	r {
		loop {
			yield(n);
			n = n + 1;
		}
	}
