Following the same reasoning, wouldn't one always stay with R 0.14 or
similar?  Note that e.g. requiring Perl 5.005 only has implications for
*developers* and not for users because we have no dependency on Perl at
run-time.  And the hope would be that developers have access to software
which is 4 years old and typically available in pre-packaged binaries.
