If there's a REPL, there aren't any phases.  The REPL keeps shifting back
and forth between syntax and semantics.

If you're telling me that the only way I can reasonably understand hygienic
macros is by thinking about different phases, that sounds like a good reason
to leave them out of WG1-Scheme, which maybe we should start calling
"REPL Scheme" to keep everyone's eyes on the ball about this!
