I think I mentioned this off-list (by accident, replying on my phone) & not
sure if it's already been addressed, but should we implement these sort of
sorts via std::tie and tuple's op<?

return std::tie(getTypeID(LHS.first->getType()), LHS.second) <
std::tie(getTypeID(RHS.first->getType()), RHS.second);
