Is it possible to generate unique fields and members with 
recursive template mixins?

Each mixin has their own scope even if outer scope shadows their 
scope. So could it be possible to generate template methods that 
can access members in their own scopes? Assuming the members are 
dispatches to unique aliases of static functions, methods 
accessing fields of unique types of both structs and classes.

Basically my use case would be something of the nature of the 
following (ofc I haven't gotten this working so it is mix of 
pseudo code and some bits of real D):

alias Data = AliasSeq!(POD1,POD2,POD3/*etc*/); //List of 
processed data types
alias Callables = 
AliasSeq!(AliasSeq!(function,another),someClass,SomeStruct); 
//processors

Processor!(Data,Callables) dataProcessor;

dataProcessor.simulate!float(1.5f);

class SomeClass(Callables)
{
recursive mixin?
}

Processor(alias Data, alias Callables)
{
    SomeClass!Callables processors;

    void simulate(parameterType...)(parameterType param)
    {
        foreach(callable; Callables)
        {
            static if(/* if right parameters */)
            {
                //Generate calls to each applicable processor
                processors!callable(param);
            }
        }
    }
}

If this is completely impossible with recursive mixin templates, 
is there another feasible solution for my use case beyond manual 
writing?

I don't fully understand the question but my answer is yes, D can do 
this as well. :p
