@headinthebox I don't even understand what's going on there...
@thomasdietert @headinthebox the length of a tuple is of course not the length of a string ...
@headinthebox @jnfrd @thomasdietert Very fucking obviously 0. Disingenuity.
@dibblego @headinthebox @jnfrd @thomasdietert Wow, as a noob both those examples are unexpected. So Haskell's competing with Scala puzzlers?
@japgolly @headinthebox @jnfrd @thomasdietert Use the types, not some vague, unreliable idea of intuition.
@dibblego @headinthebox @jnfrd @thomasdietert [Foldable t a -> Int] is vague. If it counts fold invocations, why isn't length of tuple2, 2?
@japgolly @headinthebox @jnfrd @thomasdietert length (a, b) does not read "length of a pair."
Types.
@dibblego @headinthebox @jnfrd @thomasdietert Oh its (a,b) not (a,a), der. Ok whatever its Foldable is, it's not going be what I expected.
@japgolly @headinthebox @jnfrd @thomasdietert The Foldable for ((,) t) must be exactly what this sentence impies it to be.
