[racket-dev] Quick poll

In XREPL, I followed the CL convention for "identifiers" that evaluate
to past results: ^, ^^, ^^^, etc.  CL uses *, which won't work in

Another alternative is what Guile does, use a number instead: $1, $2,
$3, etc.

Any opinions or personal preference in favor of one or the other?
