I wonder whether anyone has used "otherwise" for this. It'd be a simple alias for "else", but it'd certainly sound natural:

    if (X) { doY(); }
    otherwise { doZ(); }

Towards the bottom of the article there is a example of MAD[0] that uses something similar, and there is also the John McCarthy proposal which also uses otherwise. I could imagine it being used in a language that had a tight connection to maths as otherwise is often used there.

Oh, right, the article...
