[Rails-devel] Interfaces in method signatures

[Brett <wak...@ea...>]

The other change I've committed tonight that seemed good to dedicate a
separate e-mail toward is this:

I've removed the usage of interfaces as arguments or return types as
much as possible.

My reasoning is this:  Interfaces are not real objects and therefore
should only be mentioned when real objects are implementing an
interface. The real objects implementing the interface ought to be the
arguments and return types of methods.

Take a look at the interfaces in the Java API, List is a good one, and
you'll notice that an interface is never an argument or a return type.
