"Tri-state" logic gate outputs can do one of three things:
1) They can drive the voltage to 0.0 "0"
2) They can drive the voltage to VCC "1"
3)

Oh, right I see you also thought of that.
(Sorry, didnt read your entire mail.)

Thanks for the suggestions, although I'll probably continue to use:
var1 = 17
var1 = func1(var1)
print var1
and have func1 return the input value if no change is required.
It's *almost* as nice as if there was a Nochange value available..

No. but if you must, you can emulate that using properties or
__getattr__/__setattr__- of course then limited to classes, but writen
c.var1 instead of var1
Has anyone else felt a desire for a 'nochange' value
resembling the 'Z'-state of a electronic tri-state output?
var1 = 17
var1 = func1() # func1() returns 'nochange' this time
print var1 # prints 17
It would be equivalent to:
var1 = 17
var2, bool1 = func1()
if bool1:
var1 = var2
