My understanding of contexts was that it is roughly the "{}" block in
c++ code - the scope where variables are defined. If that's true then
if/while/for ... should have their own contexts.

But for ruby for example the variable first used inside if/while/etc.
is still declared/defined after the statement:

if something
   a = 2
end
#here "a" is defined and has either value nil or 2 depending on
whether something false or true
puts a

So I wonder whether python has the same rule.
