but haskell is still rad

• laziness - Derivation is all lazy.
• monads - Pass actions to UI as IO (), collect a list of [CmdT] before execution, manipulate unevaluated derivers as [DeriveT m [Score.Event]], etc.
• syntax - Just about never gets in my way. Easy function definitions change everything.
  Currying + ($) + do = instant custom control structures without even trying.
• lock free - Multi threaded program, but haven't had a threading bug yet.
• alias free - Haven't had any of those bugs either.
• explicit state - All state in Ui.State and Cmd.State. Nothing dangling anywhere.
• ghci - Rapidly iterate on tests, especially since compilation is so slow. I tend to type :r at the prompt instead of make build/seq!
• hint / ghc api - Extend the program on the fly, also handy for debugging.
• fun with types - Liberal use of newtypes, Signal phantom types, and I hope to do something more advanced some day...
• heap compiler - Makes neat graphs! Apparently can work in realtime!
• fun! - I'm a composer, so I like to compose while I compose.
