Well I did not want to start a new discussion, as I have to admitt
that I do not have the time for it. Python forced me to solve both
problems you stated in different ways and it let to clearness most
of the time:

	c=complicatedExpression
	long[c]=long[c]+1

And using a method to deal with a 20MBmutableVariabel seems to be
right for me, because it might have other practical problems.
