[inseperable differences up to perl 5.004_02]perl-5.004_02

[editor's note - this list of differences was built manually, so is
either a little inaccurate or the most well preened out of the
"unapplied changes" lists so far.  It certainly didn't get the usual
injection of message bodies.

The aim of these changes is to give you a vector for finding a list
message if you have an annotate operation hit this commit]

    That doesn't look quite right to me.  When provided a literal, you
    should point at the actual literal (which normally has a global
    lifetime), rather than making a mortal copy of it and pointing at
    that.  The mortal copy will be destroyed at the next statement
    boundary, and you'll be left with a dangling pointer when you
    unpack().

    You're doing the very thing the XXX comment above was intended to
    highlight.

    I do agree that literals should be pack('p')-able. So, I'd suggest
    the change be modified [...]
