If I type 'perl' on the command line, the resulting program doesn't allow Perl6 syntax.

As a matter of courtesy and common sense, we install Rakudo with the perl6 executable name, to avoid name clashes with the Perl 5 compiler.

Using that courtesy and common sense against us ist just being an asshole.

Also if you don't care about Perl 6, why do you answer Perl 6 nodes at all?
