I think this is git-head only regression. Because the OP code cannot compile
with 2.065:

$ dmd -run test
test.d(10): Error: function test.foo (ref const(S) s) is not callable using
argument types (S)
test.d(16): Error: template instance test.A.__ctor!() error instantiating

(Assignment expression is changed to lvalue in git-head, by fixing issue 12211)
