1. [New issue] PythonDictionary.Contains(KeyValuePair) doesn't check value
http://ironpython.codeplex.com/workitem/33904
User rumzeus has proposed the issue:

"PythonDictionary implements ICollection<KeyValuePair<TKey,TValue>> which has a method bool Contains(KeyValuePair<TKey, TValue> kvp). The current implementation only checks if the key is contained.

In contrast the System.Collections.Generic.Dictionary<TKey, TValue> implementation checks both the key and the value.

Is this intentional?

There is already a ContainsKey(TKey key) method that can be used if the current behaviour is desired.

Tthe documentation says: "Implementations can vary in how they determine equality of objects". So I guess this is not strictly wrong. It seems quite surprising though.
