struct Test {
    void hello() {}
}
void main() {
    Test t;
    string m = "hello";
    __traits(getMember, t, m)(); // line 7
}


dmd 2.042 gives:

test.d(7): Error: string expected as second argument of __traits getMember
instead of m
test.d(7): Error: function expected before (), not false of type bool


Defining m as const,immutable or enum string avoids this error. So those two
error messages are bad. Something better can be:

test.d(7): Error: the second argument of __traits getMember must be a not
mutable string.
