Hello Thomas, Monday, October 9, 2006, 3:47:05 PM, you wrote:
constraints on its type. Rather than being just any type that is an instance of A, I want to do a runtime check and do something different
it's a sort of problem that bites me many times when i start to wrote Streams library :) although you said that you discovered the dictionaries mechanism, i propose you to read http://haskell.org/haskellwiki/OOP_vs_type_classes page where you can find something that you don't yet know -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
