Re: daitch_mokotoff module

I pushed this after some mostly-cosmetic fiddling.  Most of the

Spoke too soon [1]:

pipit appears to be running a reasonably current system (RHEL8), so
the claim that "open" is a Perl core module appears false.  We need
to rewrite this to not use that.

I think it is a core module (See <https://metacpan.org/pod/open>) but it appears that some packagers have separated it out for reasons that aren't entirely obvious:

andrew@emma:~ $ rpm -q -l -f /usr/share/perl5/open.pm
/usr/share/man/man3/open.3pm.gz
/usr/share/perl5/open.pm
