Bug 15396 – static immutable not recognized as constant within switch statement

Test case: ````` static immutable Foo = "Foobar"; void main (string[] args) { foreach (arg; args) { switch (arg) { case Foo: assert(0); default: continue; } } } ````` This should be accepted by the compiler but it currently produces: test.d(9): Error: case must be a string or an integral constant, not Foo Tested with 2.066 and 2.069.
