Using a variable name used in a child scope [duplicate]

Answer 1

Something I noticed that was not noted here. This will compile:

for (int i = 0; i < 10; i++)
{
    int a = i * 2;
}
for (int i = 0; i < 5; i++)
{
    int b = i * 2;
}

Taken together, these design decisions seem inconsistent, or at least oddly restrictive and permissive, respectively.
