> By the same logic, if there's an infinite argument to hypot(), it doesn't matter what any other argument is - the result is +inf regardless.

Yep, that's what IEEE 754-2008 says for the two-argument case, so I think that's the logic that should be followed in the many-argument case: if any of the inputs is an infinity, the output should be infinity.

From section 9.2.1 of IEEE 754:

> For the hypot function, hypot(±0, ±0) is +0, hypot(± , qNaN) is + , and
> hypot(qNaN, ± ) is + .
