Something like this:

import std.traits : ParameterIdentifierTuple;

class Foo
{
     int a;
     int b;

     this(int a, int b)
     {
         static foreach (name ; ParameterIdentifierTuple!(__ctor))
             __traits(getMember, this, name) = mixin(name);
     }
}

void main()
{
     auto f = new Foo(2, 3);
     assert(f.a == 2);
     assert(f.b == 3);
}
