Type Names

I picked up a lot of interesting knowledge about C# in the course of developing and testing a parser for the language. I'll try to post a few tidbits as they come to mind again.

One nice tidbit is how to create new short type names without having to specify the full name of every non-primitive type, especially inside of generic type names.

Normally, using "using" to create a new type name, even in the presence of the appropriate namespace import, one has to fully qualify every type name that is not a keyword.

using System.Collections.Generic;
using T = System.Collections.Generic.List<string>

However, if the "using" is inside a namespace, then it will utilize any imports located in an outer namespace.

using System.Collections.Generic;

namespace MyCompany
{
    using T = List<string>;
}

Funny one!

Doesn't this also change the effective scoping of the alias?
