Class Field Size/Offsets

[Maxime Chevalier]

Your example works but my use case doesn't and I have no idea why:

class C { int a; }

struct Foo
{
     void foo(string className, string fieldName)()
     {
         mixin("auto sz = " ~ className ~ "." ~ fieldName ~ 
".sizeof;");

         writefln("sz: %s", sz);
     }
}

static this()
{
     Foo f;

     f.foo!("C", "a");
}

Produces:

Error: this for a needs to be type C not type Foo
Error: template instance Foo.foo!("C", "a") error instantiating
