Lang.NEXT 2012. As a first look, I wanted to try generate 
serialization code at compile time.

Here's the class:
class MyObject
{
     public int m_id;
     public Data m_data;
     public bool AutoDelete;
     public int RefCount;

mixin(AddStreamSerialization!(MyObject));
}

My template works with a struct but when I try to mixin my 
template in a class, I get compile error because T.tupleof.length 
returns 0.

Here's the whole code:

For what it's worth, dmd 2.059 (it seems you are using v2.042) 
gives this message:

serial.d(21): Error: class serial.MyObject no size yet for 
forward reference
serial.d(11): Error: template instance 
serial.GenerateFieldSerialization!(MyObject,0,"m_id","m_data","AMethod","AutoDelete","AnotherMethod","RefCount","Method1","toString","toHash","opCmp","opEquals",
Monitor","factory") 
error instantiating

According to Kenji Hara, "tupleof property requires complete 
semantic analysis to get the fields of a type."

If you haven't solved your problem yet, you may try the 
workaround described or have a look at the result of googling 
this:

Reading the bug thread, I am wondering why my template worked in 
a struct but not inside a class.

Anyway, I decided to move my mixin outside the struct/class and 
abuse UFCS instead. Now everything works like a charm :)
