I was just trying it Andy, strings are about the same, the following
shows about 75% more iterations per second using the constant:

constant x=3D{'\t','\n','\r'}
integer a,b
atom t
	t=3Dtime()+1
	a=3D0
	while t>time() do
		if find(1,{'\t','\n','\r'}) then
		end if
		a+=3D1
	end while
	t=3Dtime()+1
	b=3D0
	while t>time() do
		if find(1,x) then
		end if
		b+=3D1
	end while
	printf(1,"inline:%d constant:%d ration %g",{a,b,b/a})
if getc(0) then end if

Thanks, it's always handy to know that kind of stuff

PS I suspect if Rob tried to optimise such cases it would make the
average program slower.
