[Haskell-cafe] Is using Data.Dynamic considered a no-go?

Haskell seems to have pretty strong support for dynamic casting using
Data.Typeable and Data.Dynamic.
All kinds of funky dynamic programming seems to be possible with these

Is this considered as being as bad as - say - unsafePerformIO? What kind of
evil is lurking here?
