typeof(null) a;
    const typeof(null) b = a;
    a = b;
    assert(a == b);

Only the first line of the above actually compiles. The others complain:

cannot implicitly convert expression (a) of type typeof(null) to typeof(null)
cannot implicitly convert expression (b) of type typeof(null) to typeof(null)
incompatible types for ((a) == (b)): 'typeof(null)' and 'typeof(null)'


In addition to typeof(null) not being implicitly castable to
const(typeof(null)), and vice versa, the error message is misleading - no
indication of constness is given in the error messages.

Another thing that fails with typeof(null):

assert(is(typeof(null) : const(typeof(null))));
