This is one of several gists I've written that relate to several distinct tentative proposals for 6.d that make sense both independently and together.

This gist discusses a long conjectured feature that would work nicely with the other proposals:

Others include:

* [Implicit/explicit mutation in 6.c]().

----

In 6.c one can write two methods thus:

    multi method m (... --> self) {
        ...
    }
    multi method m (... --> SELF) {
        ... # body is identical to body of the `--> self` method above.
    }

This proposal is to support:

    multi method m (... --> self),
    multi method m (... --> SELF) {
        ... # body is identical for both method signatures.
    }

or something similar.
