Why not:

function mx(object x, sequence s)
	return match(x, s)
end function
global function match(object x, sequence s)
	if atom(x) then
		x = {x}
	end if
	if length(x) = 0 then
		return 0
	end if
	return mx(x, s)
end function

That would get you almost exactly what you want, at the price of including one
more file into your program(s). No need to type repeatedly like that anymore ;]
