[IronPython] int64/long incompatibility in dictionary lookup

[Dino Viehland]

I don't think it's a known issue - but it's because we don't have code that unifies the Int64's hashing w/ long's hashing though.  We should probably add that for a smoother .NET interop story.

I've filed this as CodePlex bug #17799 (http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=17799).  Thanks for the report.

Hi all,

is the following a known issue?

>>> x = System.Int64(8591464408876390743)
>>> y = long(x)
>>> x == y
True
>>> d = {x:3}
>>> d[x]
3
>>> d[y]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 8591464408876390743

happens in both IPy 1.1.2 and 2.0b4

thanks
Ronnie
