By application of the inductive hypothesis, I propose:
List foo is_a List = (List) new create allocate ArrayList() is_a List as List
My God. Think of the productivity.
Here's a mental exercise: every time you use your IDE to generate a bunch of boilerplate java code, think to yourself: why isn't the compiler doing this? My conclusion is that it is primarily due to a lack of two things: type inference and closures.
What's that saying about arguments and the internets?
