Happy almost anniversary, bug!
Well, what Adam uploaded doesn't actually fix the problem! It still doesn't
implement the method, it dies when you call it, and so of course *that* didn't
fix this problem.

Me!
Back when this came up, I said that the solution was to patch dumpvar.pl to
emit some "(and this part failed)" marker when a part of a dump failed, so that
the rest could continue. Nobody did that, so I have. I just pushed it to
branch rjbs/dumpvar-eval.
With that change, this program:
use File::HomeDir;
require "code/perl5/lib/dumpvar.pl";
dumpValue({ x => \%~, z => [ 1, 2, 3 ] });
Now emits:
'x' => HASH(0x7f8c3a9ccfa8)
<< value could not be dumped: You can't FIRSTKEY with the %~ hash at code/perl5/lib/dumpvar.pl line 217.
>>
'z' => ARRAY(0x7f8c3a8298e0)
0 1
1 2
2 3
If no one sees a reason to object, I will apply this to blead soon.
