Exactly. My main desire to see a module system in the language is because it's so fundamental to portability; we want to be able to share libraries, to end this situation of every implementation having their own (often incompatible, but that's another issue that the SRFIs are slowly addressing) version of every useful library under the sun. > Module system can be in a language with a simple form as in John's > proposal, or can be outside of the core language as a separately > defined meta language (maybe in SRFI).

I think that's entirely reasonable!
