Description Andrei Alexandrescu 2009-10-08 11:20:15 UTC 
Consider:

    int x, y;
    (true ? x : y) += 5;

This code fails with:

Error: conditional expression true ? x : y is not a modifiable lvalue

When both branches in a ternary expression are lvalues of the same type, the result must be an lvalue.
