[Zope-dev] the ZCA API decision

[Martijn Faassen]

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
