He's being oblique.  R5RS doesn't define any of the libraries or extra
features you might consider essential for day-to-day programming.  There
are certainly mature, useful Scheme implementations around --
interpreters and compilers.  And the SRFIs define a bunch of standard
interfaces for libraries.

Another slant is that Perl is to Common Lisp as Python is to Scheme.  CL
has got every feature that anyone thought would be useful.  Scheme has
got a minimal set of features that everyone agreed were necessary.
