Serialization/deserialization of templated class

[Dmitry Solomennikov via Digitalmars-d]

Hi, guys!

I have templated classes like this:

class Some(T1) {
   T1 value;
   this(T1 _value){
     value = _value;
   }
}
class Pair(T1, T2) {
   T1 first;
   T2 second;
   this(T1 _first, T2 _second){
     first = _first;
     second = _second;
   }
}

and a lot of serialised data, which I have to read and 
instantiate into given classes.
Serialized data looks like this: 'Some(Pair("df", 5.0))' or 
'Pair(Some(true), 11)', i.e. order of structs, its types and 
inclusion order are unknown at compile time.

I know there are several serialisation libraries, but I found 
they work only with non-templated classes, like:

class Foo {
   int a;
}

I can read input data and parse it, but have no idea how to 
construct object of templated class in this situation. Please 
give a hint.
