if you are running a Debian-based system, you could try installing the
Debian Rakudo package from either the "stretch (testing)" or "sid

is in progress to get more recent Rakudo releases packaged.

Hope that helps a bit.

Cheers,

Paul

Re: Need help with Nil values

You could just do:

method new (Str $value?) { ... } # makes value optional

and then not pass anything to .new.
