Dynamic imports throws an exception

[simplicbe]

Exception message:

Invoke() takes exactly 4 arguments (1 given)

Code for reproducing the error

from importlib import import_module
globals()['defaultdict'] = getattr(import_module('collections'), 'defaultdict')
print defaultdict
# Ausgabe: <type '_collections.defaultdict'>

I observed similar issue when importing unittest .
Exception is thrown in IronPythonLanguage.ResolveImport delegate when calling object builtin = IronPython.Modules.Builtin.__import__(context, moduleName, globals, locals, fromlist, -1);

Wen commented out scope.SetVariable("__import__", new ImportDelegate(ResolveImport)); in 'IronPythonLanguage.CreateEngine` it works without exception and IronPython resolver is able to resolve imports properly

I'll take a look at it today

I used project added in this branch https://github.com/AnritsuSolutionsSK/simplic-dlr/tree/Python_StdLib_example
When issue solved this could be added as next example how to incorporate python stdlib.

Good point. Would you like to add it with a PR?

I expected to add it as PR when issue resolved but I can add it, it is easy to close without merging.
