It's just a matter of readability, e.g. having a variable declared in
two blocks with the same name can cause you a lot of headache:
So don't allow identical names.
Ada allows exactly this feature (declaration within a block) and it is
extremely simple and not the least confusing. It's also an easy and
error-free way to manage dynamic memory allocation without using
pointers.
