I am slightly as that will take way too much screen lines. It
already has 50 lines. I do not want to scroll more (unnecessary)
Usually I know what I am looking for
Can -V be doubled to -VV to allow this? In which case every section
should list any special on a single line. That would cause the current
-V to double the line count to 97 lines
As a side note, this might break Config::Perl::V, but I should be able
to fix that when you decide to push this along
What you might want is a shell-alias that does something like
% perl -MConfig::Perl::V=myconfig -E'$a=myconfig->{build}{options};say for sort grep {$a->{$_}}keys%{$a}'
