Which raises an interesting question...

To what extent does the push to add new procedures
to the R6RS, including procedures that are simple
compositions of other R6RS procedures, derive from
fear that these procedures would be too slow if
Scheme programmers were to write them themselves
or to use a portable reference implementation?

In other words, how much of the growing size of
the R6RS can be blamed on the Scheme community's
habit of using interpreters instead of compilers?
