We do currently use $1 for params, so allowing dollar in the middle
seems better. However, I need to see multiple people who need it before
I would say OK. If we go adding things because _one_ person wants it,
we will end up with a mess. Someone is working on an
Oracle-compatibility parser. It would be OK in there.
