in thread Does Perl 5 (or 6?) need another built-in variable for the -F switch?

Well, at least perl should know which command line parameters where used when it was invoked :) and as the proposed hash %^C was supposed to be populated by perl itself, this should work out fine. This hash should then, IMO, include the command line parameters set via PERL5OPT.

Mind you, I have no idea how difficult it would be to patch that into perl, I just said I liked the idea.

    In that case, you rather want an array of pairs instead of a hash. There are switches that can be used multiple times (-M, among others), and some switches interact and their order is relevant (-l and -0 for instance).

      If -M (for example) were used multiple times, the %^C hash would look like this:

      %^C = ( M => [ 'strict', 'Data::Dumper', 'Getopt::Long' ], # ..... );
