This is a bug report for perl from perl-diddler@tlinx.org,
generated with the help of perlbug 1.40 running under perl 5.22.0.


-----------------------------------------------------------------
[Please describe your issue here]

In the file lib/utf8.pm, it says, under BUGS:

   One can have Unicode in identifier names, but not in package/class or
   subroutine names.  While some limited functionality towards this does
   exist as of Perl 5.8.0, that is more accidental than designed; use of
   Unicode for the said purposes is unsupported.
---

Hasn't perl's unicode support come a bit farther than what was
provided in 5.8.0?  I was under the impression that any "valid-for-class"
UTF-8 characters were available for use anywhere in a source
that had a 'use utf8' in its "header"?  

I've been using it it in functions and variable names for years
now (though haven't tried it with classes/packages, I'd be surprised
if they didn't handle unicode as well).

Please tell me this is an outdated "doco" (cf. typo").
