digitalmars.D.learn - How to read from an input stream generically?

What can I use instead of the din.readf line below to be able to read 
any type in that generic function?
import std.cstream;
struct MyType
{}
void generic(T)()
{
     T var;
     dout.writef("Please enter a value of type %s: ", T.stringof);
     din.readf(&var);  // <-- Runtime ERROR for MyType
}
void main()
{
     generic!int();
     generic!MyType();
}
I am looking for a substitute for C++'s operator>> overloads for user 
types. I could of course implement a static read(Stream) function for my 
types, but not for the fundamental types.
Thank you,
Ali
