Typedef really doesn't work.

import std.typecons;

alias Int = Typedef!(int);

unittest
{
    Int a, b;
    a += b;
}

typecons.d-mixin-3918(3918): Error: incompatible types for
(this.Typedef_payload) += (v)): 'int' and 'Typedef!(int, 0)'
/d32/f264.d(8): Error: template instance std.typecons.Typedef!(int,
0).Typedef.Proxy!(Typedef_payload).opOpAssign!("+", Typedef!(int, 0),
Typedef!(int, 0)) error instantiating
/d32/f264.d(8): Error: 'a += b' is not a scalar, it is a Typedef!(int, 0)
/d32/f264.d(8): Error: 'a' is not of arithmetic type, it is a Typedef!(int, 0)
/d32/f264.d(8): Error: 'b' is not of arithmetic type, it is a Typedef!(int, 0)
