Why C# doesn't have extension properties

time to read 1 min | 98 words

I just run into this problem, and I came up with a different reason than the usual one. C# simply doesn't have the concept of indexed properties. This is not legal C# code:

public static string Items[string something]
{
    get { return something; }
}

I think you can do that with VB.Net, and I am certain that C++ supports it.

The interesting part is that I run into it while building a DSL. The limit of the implementation language has actually limited the DSL itself.
