All I have are the CTFE status threads, where one can see what I 
consider a working feature set.
What is planed is simple to state: "Re-implement the full 
functionality of the current ctfe-interpreter in the new IR-based 
system"

It is hard for me to say in advance which features will be 
working, or indeed regress next.
Since the interactions between features form a complex system 
which by definition is  very hard to predict.

My current goal is to make complex structs work.
Meaning structs with other structs inside it.
For example
struct SimpleStruct
{
   float c;
   uint a;
   ulong b;
}

struct complexStruct {
   SimpleStruct[2] a;
   complexStruct* next;
}

The complex struct will currently produce a vaild IR type.
But will generate invalid code, since the ABI is currently in the 
process of changing.
And different parts of the code will interpret the data 
differently.

On top of that I have to rebuild a few of the expression handling 
routines to switch from the old reference based  ABI to the new 
hybrid ABI.
