Those restrictions are the best we can get so far, but they did lead to
confusion once in a while (which I'd be happy to avoid in the future).

Can you confirm that returning empty string and 0 for NULL is expected
behavior and not seen as a bug?

For us it's a minor issue now but I think that "everybody else" did
write very little code - if any at all - based on this behavior and it
would be very easy to to fix it in a backwards compatible way ( i.e. `if
not var` instead of `if var != 0`).

I'm going to be quiet now :-)
