I was talking to a friend about the differences between the type systems of Haskell and Java. He asked me what Haskell's could do that Java's couldn't, and I realized that I didn't know.
After thinking for a while, I came up with a very short list of minor differences. Not being heavy into type…

One thing that has always infuriated me about SSIS is the fact that every package has three different type systems; to give you an idea of what I am talking about consider the following:
The SSIS dataflow's type system is made up of types called DT_* (e.g. DT_STR, DT_I4)
The SSIS variable…

Assuming a language with some inherent type safety (e.g., not JavaScript):
Given a method that accepts a SuperType, we know that in most cases wherein we might be tempted to perform type testing to pick an action:
public void DoSomethingTo(SuperType o) {
if (o isa SubTypeA) {
o.doSomethingA()
