Without getting into the meat of this srfi, the names seem awkward.
Most obviously, there is a set! operator, which conflicts with r7rs.
The 'make' procedure conflicts with (at least) Kawa and Guile.
The 'range' name might be better saved for a procedure that returns
a "range" (sequence of integers) value.

Obviously all of these can renamed on import, but it seems rather contrary
to Scheme naming conventions.
