[IronPython] Some new bugs with asssembly loading...

Ok, but I'm not sure why my situation is different. I've tried this over
and over, and I keep getting the same behavior. The References are not
updated until I do it twice, and I can't import my assembly.
Could it be something odd about the assembly (this worked fine in ip
version 0.9.6)? In fact, if I simply run the 0.9.6 version of IP, it
still works just fine.

It looks like I've got the most up-to-date CLR. 
Other potential things that could be different?

Hi Steven,

I am not observing the first and second set of the problems you
reported. My assembly has name c.d.e.dll and adding reference to it
works just fine. It shows up in the References right away also.

>>> import clr
>>> clr.AddReferenceToFile("D:\\Ip\\IronPython\\c.d.e.dll")
>>> clr.References
(mscorlib, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089, System, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089, c.d.e,
Version=0.0.0.0, Culture=neutral, PublicKeyToken=null)

As for the import, we do have a bug that affects global-level types in
the referenced assembly. Types that are enclosed in the namespace can be
imported without problems:

>>> import N
>>> N.C.M(1,2)
2

Where the assembly c.d.e.dll was compiled from:

namespace N {
public class C {
    public static int M(int a, int b) {
        return a * b;
    }
}
}

Excluding the namespace N will break if I try to do corresponding:

>>> import C
< Exception here >

A number of bugs seem to have been introduced with the new assembly
loading code:

First off, my assemblies will no longer load if they're named x.y (for
instance, I was using an assembly that was named Aforge.Imaging). This
will break since the code does a .split('.') to find all the names to
load.

Second, the first time that I call AddReferenceToFile doesn't effect the
clr.References list at all, but it adds it the second time. See the
following snippet.

Version=2.2.0.27774, Culture=neutral, PublicKeyToken=null)
>>> 
----------------

Third, this breaks when I try to import the file. (No module named
AForgeImaging):

>>> import AForgeImaging
Traceback (most recent call last):
  File , line 0, in input##12
ImportError: No module named AForgeImaging
>>>

Any assistance would be appreciated...
