| Just walk through an execution trace table and see for yourself.
| Use the concrete examples provided on this link. See how the
| execution trace table differs when the WillHalt() function is run
| using the LoopIfHalts() function as input, on each of these two
| different variations of the WillHalt() function.
|
| (1) bool WillHalt(M, w)
| (2) void WillHalt(M, w)
|
| In the first case WillHalt can not correctly determine if
LoopIfHalts()
| will halt or not. In the second case LoopIfHalts() won't even
compile
| because it is a syntax error to check the return value of a
function that
| has no return value.
Sorry Peter, That did not answer my question.
