$ perl -lwe 'use Time::HiRes 01.99; print "ok"'
ok

This is a funny result considering that Time::HiRes is at version 1.9719
on this system.  Look at some related version numbers:

$ perl -lwe 'use Time::HiRes 1.99; print "ok"'
Time::HiRes version 1.99 required--this is only version 1.9719 at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
$ perl -lwe 'use Time::HiRes 010.99; print "ok"'
Time::HiRes version 8 required--this is only version 1.9719 at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
$ perl -lwe 'use Time::HiRes +01.99; print "ok"'
Time::HiRes version 199 required--this is only version 1.9719 at /usr/local/share/perl/5.10.0/Exporter/Heavy.pm line 123.
BEGIN failed--compilation aborted at -e line 1.
$ perl -lwe 'use Time::HiRes 1,99; print "ok"'
Time::HiRes version 99 required--this is only version 1.9719 at /usr/local/share/perl/5.10.0/Exporter/Heavy.pm line 123.
BEGIN failed--compilation aborted at -e line 1.

Apparently, in "01.99", the "01" is being interpreted as an octal number,
and the ".99" is being interpreted as "0.99" and being passed to import.
(You can't see the effect of the 0.99 in this sequence, but it's visible
if you write your own import.)  This is unlike the parsing of "01.99"
in ordinary code, where it parses like "(01).(99)" and results in the
string "199".  It's a confusing difference.  Bug?  Not sure.
