Ubuntu 15.04, x86_64

Test case:

var a = "foo";
switch(a) {
    case true ? "foo" : "bar":
        print("OK");
        break;
}

Output:

    case true ? "foo" : "bar":
                             ^
ERROR: Ln 3, Col 30: Expected either ';' or newline token

According to ecma5, any expression can stand in a case clause after the 'case' keyword but ternary statements are rejected in jerry.

I think we can close this. Check out #666.
