Should .^methods be curried with the invocant?

Consider this case: class A { method m { say 'OH HAI' } }; my $m = A.new.^methods(:local).[0]; How should I invoke $m? In current Rakudo this works: $m(A.new); # supply the invocant as first argument But shouldn't be just $m() (invocant magically curried) or may $m(A.new:) (invocant not cur

How does List.map: { .say } work?

Hi, the current spec doesn't allow immutable containers to call .map with a block that implicitly uses $_ as an implicit parameter. Here's why: S06 says > The C<$_> variable functions as a placeholder in a block without any > other placeholders or signature. Any bare block without placeholders
