This is a bug report for perl from eserte@biokovo-amd64.herceg.de,
generated with the help of perlbug 1.39 running under perl 5.10.1.


-----------------------------------------------------------------
There's a new warning when just using Safe.pm in some ways. I
could reproduce it with the following piece of code

require Safe;
Safe->new;
__END__

put into a file XXX.pm and then using it like this:

$ /usr/perl-5.10.0-3220-gf9961a0/bin/perl -w -MXXX -e1
Name "version::CLASS" used only once: possible typo at /usr/perl-5.10.0-3220-gf9961a0/lib/5.10.1/amd64-freebsd/Safe.pm line 251.

I did a bisect, and then problem appeared in 1c92ff99e7dfbea7d6a8aebe7194d6251fb1b810
in blead.

Regards,
    Slaven
