Hypot is not consistent?

Just saw this: julia> Base.infer_effects(hypot, NTuple{2, Float64}) (!c,+e,!n,+t,+s,+m,+u,+o,+r) How come hypot() is not consistent? Is this a problem of inference not being precise, or is there actually something that makes hypot() inconsistent? hypot() not being consistent doesn’t really matter to me, just curious…
