I expect this small program to throw an Exception:

But it just outputs:

Is it a bug or is it me who's doing something wrong?

Looking at the implementation, it looks like enforceNotJagged was just never implemented for transposed (only transversed).

It was suggested when transposed was fixed to include opIndex, but never implemented.

Maybe I'm too naive, but isn't it easy to implement it just the same way, it is done with transverse? That is: putting the "static if"-part from the constructor there in the constructor of Transposed?

You're not too naive, it would be easy (I think I said as much here: https://github.com/dlang/phobos/pull/5805#issuecomment-341234846). It just wasn't done in that pull (which was focused on a different problem).

Please feel free to submit a fix!
