LambdaScientist questions

• In Haskell how can I match a type class with an instance of that type class?
• Why will a IO nested in other monads not execute? Is there a way to force them to?
• How to implement something like std::copy_if but apply a function before inserting into a different container
• Creating a fold that allows the type to change after each repeated function call, in order to call a function n times without recursion
