          Issue ID: 17141
           Summary: CommonType!(dchar, char) returns uint
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

Should return dchar.

This breaks range functions like chain, example:

string name = "Jack";
auto app = appender!string();
app.put(
    chain(name, toChars(10))
);
