How to reference an indexer member of a class in C# comments
Static Indexers?
As it stands, I have to write my code like this
internal class ReportMap {
    static internal ReportMap Instance {
        get { return reportMap; }
    }
    internal Type this[char c] {
        get { return data[c]; }
    }
    // private parts
    static Dictionary<char, Type> data =
        new Dictionary<char, Type>();
    ReportMap() {
        data.Add('S', typeof(StatusReport));
        data.Add('Q', typeof(QualityReport));
    }
    static ReportMap reportMap = new ReportMap();
}
and to access an index:
Type t = ReportMap.Instance[aChar]; // eww
Is there a specific reason this ability was left out of the language? In particular, would it be considered bad design? There is another question on this already posted, but I unfortunately do not have enough rep to comment.
