in reply to Making variables visible between calls.

sub create_f { my $func = shift; return sub { $func->("xpto"); } } my $function = create_f( sub { my $var = shift; print ">> $var <<\n" } );

It's technically possible using dynamic scoping (local), but that increases coupling. What I presented is a much better alternative.

    Yes, at the moment that is my own solution, but that forces the user to get a set of predefined parameters. It works, but not as clean as I would like it to be to the user. ;)

    Thanks

      A set? No. You could pass a hash or an object.

      Not as clean? Any method of passing arguments without using parameters would be less clean than using parameters.
