The variable name X has been used in the examples,
because the examples have been free of content.
No-one, as far as I am aware, is arguing for the use of X
_as such_, although it is at least better than _  or ~ .

This is why I keep on screaming for *real* examples.
I predict that in real examples, we can find a way to express
what we want with meaningful variable names.
