Except that a variadic hypot function is non-trivial to implement (in a way
that people expect it to behave), the one implemented above is essentially just
sugar and can overflow even though the result is inside the range of a double.
Usually hypot is implemented something like |x| * sqrt(1 + (y / x)^2) (|x| >
|y|) instead, but such a formula for a variadic hypot is probably non-trivial.
