Thanks for chipping in.

Just for the record, I'm more keen on removing the special case that
disallows this. For me it's more about POLA. I expect that anywhere
I can write an expression in SQL, that I can put a Const in its place
and not receive an error to say constants are disallowed.

I mentioned this to Andres in a meeting yesterday and it seems to be
against allowing Consts, so I seem to be losing this one.
