No. For the collections (which have opposite type needs from things like hoping for generic functions and control structures), the ability to write things like Map<Integer,Map<Integer,Double>> (poor man's sparse matrix) are a bit win for readability.
I love generics in C# (well as well as one can love a language feature like that) but the generics in Java aren't the same apparently. I haven't used Java since this addition. Any opinions from regular Java users?
