The REPL's almost an independent project. Can it be made modular, to reduce the coupling between it and the language?

Re: Simple windows code example needed

P.S. I just noticed your "long way": perl6 my_program.pl If you are invoking the script as an argument to perl6, you don't need a suffix. Windows needs the .pl suffix to decide what to do with the file. If you have Perl 5, you are likely have .pl linked to it. I'd suggest a separate value,

In some ways, the problem is an embarrassment of riches. There are so many aspects of P6 ("layers of the onion"), many of which are of no interest to people who merely have a problem to solve. Many of the concepts of P6 that are essential to its role as a language development platform are
