I thought we agreed that "," would not generate an error outside of 
backquote! At the very worst it should be an ordinary character
when not in backquote. After all, "@" doesn't get similarly wedged.
We are losing characters fast and sacrificing them for a new feature is
one thing but making them altogether illegal in certain contexts is
very restricting I think.
