Compilation errors or something else? pragma(msg) helps with debugging
generated code. You can also use unittest blocks to make sure that the
generated code is what you expect.

That one makes a user-defined type to be used as another type. The
example from the documentation is MyInt behaves exactly like an int by
forwarding int operations to 'value':
struct MyInt
{
private int value;
mixin Proxy!value;
this(int n){ value = n; }
}
MyInt n = 10;
Support for all the following operations (++, ==, *, and more) are mixed
in by Proxy:
// Enable operations that original type has.
++n;
assert(n == 11);
assert(n * 2 == 22);
