David, why not go for the ICON style returning of values:

def match (x, s)
    for index = 1 to length(x) - length(x) do
        if equal (x, s[index..index+length(x)]) then
            return index
        end if
    end for
end def

A normal call would just return the first matching value, however, imagine
what the 'each' keyword does:

printf(1, "Found match as %d", {each match(x,s)})

More readable, look at this approach:

for each match (x, s) as pos do
    s[pos] = '!'
end for

What do you all think about this feature ?
