Fix means make compatible. And the argument is for the community at large to do
it, not just those who maintain the Perl interpreter.
I recall various comments that the Perl 7 announcement has lit a fire under the
wider Perl community and a lot of people are chomping at the bit to help the
effort. Well providing compatibility updates to modules is a good use of that.
Lots of modules are in public version control and people wanting to help can
submit pull requests for them. This has happened over the years anyway.
A low-hanging fruit is that if anything doesn't work with use strict it is
updated to declare its variables and so on.
Personally I do NOT advocate that signatures or anything likely to change be
turned on by default, but simpler things unlikely to change should be like "say".
