Within a function, a given name can be either global or local, but not
Here you are expecting the compiler to interpret the first occurance of
'number' as local and the second as global. Humans can often resolve such
ambiguities correctly, but not necessarily always. So this is too much to
ask of a program and hence it is not allowed.
As Benjamin said, use two different names for the two different objects
that you need to use in the same context.
