Thanks for doing that, James.  I was thinking about taking a swing at
that very thing but I'm quite glad you beat me to it.  I had a brief
look at applying the patches to blead and the first 4 I tried don't
apply at all.

In case it's not obvious, both of the following things would need to
happen for these patches to get into the Perl core:

1.)  They need updating to apply to blead, the development stream
currently leading up to 5.20.  A snapshot of the latest development
release is at <>.

2.) The build and test must still work on ASCII systems; maintaining a
separate fork that only works on z/OS is something that could be done
by someone else somewhere else, but I can't imagine anyone interested
in trying to do that as part of Perl core development.

No one is obligated to do these things, but doing so would be one
visible sign that people interested in continued EBCDIC support in the
core are actually doing something about it.  It would only be first
steps, as ongoing signs of testing would still need to materialize.  A
perfectly reasonable alternative is that people can simply rely on the
Rocket Software port of 5.16.2 indefinitely and have another decade or
two of good Perl work on z/OS ahead of them.
