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

They are not unsafe in the way unsafePerformIO is, but I regard them as a last resort in certain situations. Still, in those situations they are very useful. -- Lennart 2009/2/12 Peter Verswyvelen <bugfact@gmail.com>:

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 "hacks". Is this considered as being as bad as - say - unsafePerformIO? What kind of evil is lurking here? Cheers, Peter
