At a quick glance at least it seems that what Z offers is a better (in the eyes of its designer) syntax. I glanced through to about the ternary operator in order to find the USP. After going back just now I found "The Why of Z" and it seems to be that text output typically needs some kind of module import:

    "First off, the import statement is clutter. Why can't the text function be built-in, perhaps?"

So it seems it's not out to solve the bigger issues of programming...
