Since SRFI-1 is implemented in Scheme the SRFI-1 replace!
is slower than the builtin replace!.

And it is no trouble to write

  (require (lib "list.ss" "1" "srfi"))

And if the extended reverse! is needed, just use

  (require (lib "list.ss" "1" "srfi")
           (prefix srfi: (only (lib "1.ss" "srfi")

This might seem like "much trouble", but when you
get used to the module system, you won't give
it much thought.
