Hi there,
I think we've had enough discussion to make a decision. Hopefully
everybody is at least reasonably happy with this:
An "adapt()" method will be added to Interface. It takes the objects to
adapt as *args, and optional but explicit 'default' and 'name' aguments.
A "utility()" method will be added to Interface. It takes optional but
explicit 'default' and 'name' arguments.
On the adapter hook (__call__) we will deprecate the implicit second
argument for defaults, with a deprecation warning. Instead, we will
require people to write out 'default=' explicitly. Otherwise its
behavior remains unchanged. I think we can motivate this change purely
because IFoo(bar, baz) really is quite surprising compared to IFoo(bar,
default=baz).
[steering group members, if you are really unhappy with this, please
speak up now. Silence is assent. :)]
Hopefully we can move forward towards implementation.
Thomas Lotze, are you happy enough with this to still help with the
implementation?
Thanks everybody for your participation in the discussion!
Regards,
Martijn
