Also, the loadfast in lne 22 to reference x could be taken out of the loop as x will always point to the same object....

That's not true; a debugger may change the value of x. Another example. I can totally remove the variable i, just using the stack, so a debugger (or, in general, having the tracing enabled) cannot even find something to change about it.

Debugging is challenging enough as it is -- why would you want to make it even more difficult?
