Really? I have no clue what that function makec clearer than tex. And
one still needs some documentation that explains what it does.

Often there often is a pretty clean way to do it with less code.

For an experienced tex speaker, indeed.
But for an average user who just wants to typeset a bit of fancy stuff,=20 programming in tex is probably not the most pleasant thing to do and=20 arguably not the most reasonable either in light of any modern language lik= e lua.
