Not quite: 

a = [1, 2, 3]
b = "I'll change"
c = "I'm static"
a.each do |b| 
	# whatever
	# can use other vars any way I want
end
# here b = 3
a.each do |;c|
	#whatever
	#can use other vars any way I want
end
# c still the same

Now I see this syntax (or my understanding of it) is broken as you
cannot specify the order in which your vars are assigned...

Maybe
a.each do |:a,b,:c,d|
 # a and c local
 # b and d "external" (outer scope)
end

It is better to mark local vars as this way all the existing code works
unmodified. I've used ':' cause I cannot think of any other semantics
for it in that position.

You see, it's still "the Ruby way" as it's just like before, only with
additional scope markers.

If we want to discriminate between variable usages, it's either this or "my"...
