`--force` flag does not work on MacBook

[KES777]

$ perlbrew --force install perl-5.40.2
Installing /Users/ek-mac/perl5/perlbrew/build/perl-5.40.2/perl-5.40.2 into ~/perl5/perlbrew/perls/perl-5.40.2

This could take a while. You can run the following command on another shell to track the status:

  tail -f ~/perl5/perlbrew/build.perl-5.40.2.log

Installation process failed. To spot any issues, check

  /Users/ek-mac/perl5/perlbrew/build.perl-5.40.2.log

If some perl tests failed and you still want to install this distribution anyway,
do:

  (cd /Users/ek-mac/perl5/perlbrew/build/perl-5.40.2/perl-5.40.2; make install)

You might also want to try upgrading patchperl before trying again:

  perlbrew install-patchperl

Generally, if you need to install a perl distribution known to have minor test
failures, do one of these commands to avoid seeing this message:

  perlbrew --notest install perl-5.40.2
  perlbrew --force install perl-5.40.2

$ perlbrew list
* perl-5.40.0
$ perlbrew use perl-5.40.2

ERROR: The installation "perl-5.40.2" is unknown.

What does the log file show after this failure?

The --force option doesn't seem to cause it to continue after a test failure. This has been the case since 4ee1149b9af29187aac7ef983caaf5f83108d9d8, but seems unintentional.

Thanks for the investigation @haarg -- that does looks unintentional to me.
