You are bringing up that old "raising-conflicts-saves-lives" argument
I've seen on the mailing list, but it doesn't apply here...

First of all, I was proposing that mzscheme never export anything but
the SRFI-1 versions -- or, alternatively, that the SRFI-1
implementation simply re-export the mzscheme versions, where
applicable (such as for reverse!).

Now, how is mzscheme reverse! different from SRFI-1 reverse! ? I see
no inherent reasons for two different versions. Do you? SRFI-1 doesn't
mandate the usage of its reference implementation, in case you want to
mention "native vs. Scheme".
