Well, that's a reasonable argument. And now that I think about it,
a parser-only node type doesn't have nearly the support overhead that
a full-fledged executable node does. So no objection to A_ArrayExpr
if you want to do that.

Uh, you missed quite a lot of others ... see CURRENT_DATE and a lot of
other productions.
