That's true. But the underscore has been with us at least since Algol,
so it isn't really perceived as punctuation by programmers. The use of ?
in predicates isn't nearly as common, although I admit that it's
suggestive. But ? is also about the only single ASCII character left
that isn't either a delimiter symbol or predefined as an operator in
Pure yet, which makes it kind of precious.

I'm undecided on this. Is matrix? x really that much easier to read and
understand than matrixp?
