Sorry about that; it was all much too long.  Briefly,

1) I saw multiple problems with C<use encoding>, leading variously to
   core dumps, panics, baffling exceptions, and odd failures.  I fear
   some idiocy of my own: that's why I'm shy at formal bug-reporting it.

2) I had next to no end of trouble testing whether $data began with BOM
   in either byte-order.  My tribulations were so severe I have to wonder
   whether I'm not somehow being brain-damaged here as well.

Is there any collective sense of how many bug reports, particularly about
C<use encoding>, this merits?  

If non-zero, should I submit just one report detailing several apparent
problems, or would several reports each containing one problem be better?

If it were only a matter of self-education and documentation improvements, 
I'd be happy to submit those patches myself--once I finally understood it.

However, I confess that Perl's I/O layers and related encoding futzing
take me so much effort to get my head around than the source code used
to back before those subsystems existed that I frankly don't know whether
I'd ever sort this out on my own. :(

Thanks,
