In addition to the things in the "Positive confirmation only" topic, this is my other major annoyance with visual assist, and it also destroys my programming flow. This is also a very old case, case=7802, nearly two years old.

I encounter this almost daily, as our mock object library works like this. I type Expect().Once().On(object).Function(&Class:Function).With(5). Everything works fine it flows nicely, I added some simlpler macros so visual assist doesn't get confused. But once I come to the function part it all breaks down, I most likely type &Class:F and press tab. It expands to &Class:Function(), and puts my cursor between the parenthesis, since its a function taking an int argument. Now to undo this effect I have to press two different keys(arrow+del+del, arrow+backspace+backspace, backspace+del or del+backspace), which is very counter productive.

I don't buy the argument that you sometimes might want to take the adress of the return value. First of all a return value is an rvalue, c++ standard 3.10-Temporaries are rvalues (See also lifetime). Secondly you cannot take an address of an rvalue, c++ standard - 5.3.1/2 The operand of & must be an lvalue. So the code is in fact not valid c++, even if some compilers might accept it.

Secondly what's wrong with the code expanding to &Class:Function at first, then when you press ( it shows the function arguments. All of this according to the positive flow and positive confirmations as I have been talking about.
