colinr@pandora~/projects/exporter-bug $ perl5.8.8 -we 'use Once; printf
"%6d: %s\n", -s, $_ for sort values %INC;'
8840: /opt/csw/share/perl/5.8.8/Carp.pm
14419: /opt/csw/share/perl/5.8.8/Exporter.pm
5488: /opt/csw/share/perl/5.8.8/base.pm
3292: /opt/csw/share/perl/5.8.8/strict.pm
2358: /opt/csw/share/perl/5.8.8/vars.pm
15879: /opt/csw/share/perl/5.8.8/warnings.pm

oh. Very different. ok, perhaps time to consider that this 5.8.8
installation is a somewhat dodgy. It's actually similar, though not
quite identical, to our 5.8.7 installation:
colinr@pandora~/projects/exporter-bug $ perl -we 'use Once; printf "%6d:
%s\n", -s, $_ for sort values %INC;'
8840: /usr/local/lib/perl5/5.8.7/Carp.pm
14419: /usr/local/lib/perl5/5.8.7/Exporter.pm
5488: /usr/local/lib/perl5/5.8.7/base.pm
3292: /usr/local/lib/perl5/5.8.7/strict.pm
2358: /usr/local/lib/perl5/5.8.7/vars.pm
15793: /usr/local/lib/perl5/5.8.7/warnings.pm
1014: /usr/local/lib/perl5/5.8.7/warnings/register.pm
101: Bar.pm
101: Foo.pm
63: Once.pm
So at this stage it looks like it's something that may well be fixed in
5.8.8 and it may just be that our 5.8.8 installation is borked for one
reason or another. It doesn't appear to be the "no warnings 'category'
works correctly with -w" fix, since the problem is still there with 'use
warnings' at the start under 5.8.7. But the next thing to do is for me
to investigate this 5.8.8 installation to see if it's unhealthy.
Thanks to all of you for your help.
