This  would mean that we have to disambiguate generic parameter lists from comparison operators across lines:

	// Is this `a<b, c>(d)`, or `(a < b); (c > (d))` ?
	a < b
	c > (d)

Maybe our existing lookahead rule is still sufficiently unlikely to misparse it (since we require a < to be followed by the type grammar, then followed by a '>.' or '>(' to parse as a generic param list), but that's something that'd have to be explored.
