Relying on a brain damaged non documented edge case was unanticipated, not the change --which had also been in beta before release.

What kind of programmer passes "" and null on a function such as this and expects ....zero in return?

And what kind of programmer does it --as he admits-- "all around the place"?

If you give right to this guy, that's a very very short and accurate interview question --no hire.
