There was a bit of SRFI-98 discussion in July 2008 about adding setenv and unsetenv, but it never went anywhere.  I think I didn't pursue it then because they are Posix but not ISO C.  So yes, SRFI-170 seems like a good place.

Can you prepare a PR against Harold's repo, at least for the document?  Thanks.

R7RS has `get-environment-variable` and `get-environment-variables`

Is `set-environment-variable` standardized anywhere? If not, would SRFI
170 be a good place for it?
