[Python-ideas] get() method for list and tuples

[Abe Dillon]

Barry, you're taking the metaphor too far. Duct typing is about presenting
a certain interface. If your function takes an object that has a get(key,
default) method, the rest doesn't matter. That's the only way in which the
object needs to resemble a duck in your function.

I'd like to +1 this proposal. It should be trivial to implement. It won't
break backward compatibility. It's intuitive. I can think of several places
I would use it. I can't think of a good reason not to include it.
