Oops, and,
so we really need to support at least ColId as the allowed set of
column alias names. (I tried changing the patch to do that, but
got a lot of shift/reduce conflicts, some of which are maybe fixable
but some seem hard to fix.)
Since capability was insufficient, I spent several times as many time as this.
It understands the very hard thing. Hardship had left traces upon this features.
I want me to still inquire.

Hiroshi Saito
