Excellent!

> I do not agree that one should go into SRFI 41bis and another into SRFi 158bis, for two reasons: (a) we don't put all foo->list procedures into SRFI 1bis, and (b) doing so would create a circular dependency, not in this case but in many cases.  For example, stream->lseq would require the SRFI 127bis to depend on SRFI 41, and lseq->stream would require SRFI 41bistttttttttttttttttt to depend on SRFI 127.  It is better to have datatypes interoperate using bog-standard object types like lists, vectors, and procedures.

That makes a lot of sense!

The more dependencies a library has, the more costly it will be to
include it into a program. Thanks to things like `eval`, a Scheme
linker is often not able to throw out seemingly unused parts of a
library.
