CodeContext is used throughout IronPython. But since I moved to IronPython RC1 I cannot get hold of one. Has anyone used IronPython RC1 and managed to use ClrModule.AddReferenceByName(...) or PythonType.__getattribute__(...) Both of them take a CodeContext and hence I can no longer use them. ...

This needs to be ignored (even if it contains other numbers.) e.g. "1" => 1 " 42 " => 42 " 3 -.X.-" => 3 " 2 3 4 5" => 2 Is there a built-in method in the .NET framework to do this? int.TryParse() is...
