[perl #120919] [BUG] Private methods in roles don't bind 'self' correctly in Rakudo

[Christian Bartolomaeus via RT]

The test in S14-roles/basic.t passes now on JVM.

Also the code from lizmat++ does not die:

$ perl6 -e 'role R { method !m(@a) { say "ok: @a[]" }; method x() { self!m((my 
%).values) } }; class C does R { }; C.x'
ok:

I haven't yet looked at src/core/IO/Local.pm or src/core/Temporal.pm
