They are very easy to overlook and mix up with regular stack variables and i've seen (and introduced myself) a number of bugs due to them.
They also often are used in buggy ways (with SMP not taken into consideration), so overlooking them during review compounds their negative effects. Putting them in front of the function isnt a big deal in exchange.
There are people who never overlook them (like yourself), but my brain is wired up differently.
Thanks,
Ingo
