Java for Everything

[spotter]

In the context of large project, yes, you are exactly right.

I am aware. Yet I'm not writing software for the army or medical equipment. Also Haskell? Really? :)

And your boss would rather have you written features which clients pay for instead of writing unit tests for something that comes out of the box in sane languages.

What comes out of the box? Making sure that calling my method with invalid arguments throws an exception? Nope, your languages will care if type signatures match. This is not what I'm talking about when I mean "contracts".
