  [t/spec] Add a test for RT#​66330 to walk.t. Also tweak a couple of tests that won't quite work; things passed into :omit and :include need to be a little more careful since they'll be invoked with Mu at some point, which in this case didn't end too well.

Works now​:

my ($meth) = Grammar.WALK(​:name<parse>); say $meth.name;
parse

And added a test to walk.t, so resolving.

Thanks,

Jonathan
