Exactly.  A related message was this: .  I had just read
Flatt's paper, which led me to think we really needed a variant of
`use-modules' to specify modules that are used only at compile-time, for
their macros.

... which isn't much of a problem I suppose.  :-)  Moving to SRFI-9 looks
like a good idea to me.

I'm not sure.  I'd prefer to use plain Scheme with SRFI-9 records in the
compiler since using GOOPS may not buy us much.
