I though maybe it would be nice in general to be able to create 
static indexed type by having a special field name pattern, but 
I will have a another look at staticMap (I don't really want 
the full staticMap into object.d though).

This is the core of staticMap, I find it problematic to do this 
kind of string mixin in object.d:

private enum staticMapExpandFactor = 150;
private string generateCases()
{
    string[staticMapExpandFactor] chunks;
    chunks[0] = q{};
    static foreach (enum i; 0 .. staticMapExpandFactor - 1)
        chunks[i + 1] = chunks[i] ~ `F!(Args[` ~ i.stringof ~ 
`]),`;
    string ret = `AliasSeq!(`;
    foreach (chunk; chunks)
        ret ~= `q{alias staticMap = AliasSeq!(` ~ chunk ~ `);},`;
    return ret ~ `)`;
}
private alias staticMapBasicCases = 
AliasSeq!(mixin(generateCases()));
