	*ptr++ += 2;
means:
	get the datum addressed by ptr;
		(increment ptr as a side-effect, AFTER getting the datum)
	add 2 to the datum;
	put the modified datum back from whence it came;
		(if any action is needed to fix side-effects, do it now)
This is figured out by following the operator precedence hierarchy.
