From the outside, the type systems of languages like Haskell and ML tend to look like a sort of archaic ecstatic religious rite. The bleeding mendicants pause as they shuffle past, sing a verse in praise of the purifying pain of strong typing, then prod themselves with pointy sticks and progress along their lonely road.
Bryan O’Sullivan, commenting on his own quotation of Yaron Minsky. I’ve heard people complain about Haskell’s type system as being too strict, but once you figure out how to get things to type check, you can actually use it like a miniature theorem prover. Which is, essentially, what it is.
Oh yeah, and it’s my birthday today.
