Whether you find yourself using them and whether they're actually necessary are two different things :) I've gotten use out of generics in "application code", but I've also been bewildered by overly-complex generics-within-generics-within-generics written by other people in application code. It's hard to be conclusive, but I wouldn't be surprised if they've done more harm than good across application contexts. |

To me, that's a shining example of the problems I've run myself into when trying to squeeze much power out of Java-style generics. I never seem to encounter similar problems in F#. Scala, it depends on how successful I am at not losing a boot in the mud.
Generic programming was born in a language whose other pioneering features were algebraic data types and an HM type system. I've never really seen a first-rate example of one that didn't come paired with at least passable examples of the others.
