Pointer to variables in D

[Victor Vicente de Carvalho]

Hi there,

In c++ one can access a pointer to a class/struct variable using 
this semantic:

struct C {
  int x;
};

int C::* ptr = &C::x;

C foo;

foo.*ptr = 10;
assert(foo.x == 10);

It is possible to do something like that on D? I've searched 
through the forum & documentation but didn't found anything.

Also, the reason of this is that I'm studying a way to map a POD 
structure based from a dynamic, data-driven structure. Something 
like "get a JSON and map it to a structure automagically". There 
is a nicer way to do that in D?
