For 3.3, I'd like to revive the tradition of listing planned large-scale
changes in the PEP.
I want to integrate dependence injection in the stdlib, specially in
libs creating sockets. This would be an optional feature.
The idea would be, for instance, that smtplib could call an optional
constructor to create a socket-like object, if some is provided.
That would break the implicit dependency with sockets, reduce
monkey-patching need, and ease testing the libs.
In general I dislike dependency injection if it's only done for
testability. With monkey patching (if done right) you can safely test
Python code without messing with your public interfaces just to make
code testable.
A clean solution that does monkey patching correctly for us, for use
within our own tests would be a better solution in my opinion.
All the best,
Michael Foord
I proposed this on the list like a year ago. Somebody else said he was
planning a PEP... not done yet, I guess.
