This is one of the best qualities of languages like Haskell, the type system promotes discovery and true reuse of code. There has even been research into specifying dependencies as 'something that implements this signature' rather than specific packages.

Yeah haskell is amazing. I'm still really looking forward to the day when somebody writes something actually useful in haskell. (Oh but pandoc, xmonad, shellcheck... in how many years?) ;-)
