[Haskell-cafe] Martin Odersky on "What's wrong with Monads"

[Jonathan Geddes]

Cafe,

I was watching a panel on languages[0] recently and Martin Odersky (the
creator of Scala) said something about Monads:

"What's wrong with Monads is that if you go into a Monad you have to change
your whole syntax from scratch. Every single line of your program changes
if you get it in or out of a Monad. They're not polymorphic so it's really
the old days of Pascal. A monomorphic type system that says 'well that's
all I do' ... there's no way to abstract over things. " [0, 53:45]

Thoughts?
