Fair point.

I'm less concerned about the "er" than about the fact that the name is
two words. People will immediately shorten it to just "replay", eg
as a part of names in the code, and I feel that that's confusing in
its own way. Maybe we could run the words together, on the precedent
of "walreceiver", but I never much liked that name either.
