Actually, it only works with numbers. Most of the complicated-looking
code just determines the type that can hold all possible results (that's
what the supertype stuff is for). That's also the reason it won't work
with strings and arrays - they don't define "+". Sorry. ^^
But yeah, it is a bit overkill. Gets handy when you want to min/max more
than two values of different types.
