[From the SDK docs]
"A local variable named 'var' cannot be declared in this scope because it
would give a different meaning to 'var', which is already used in a 'parent
or current' scope to denote something else".
although you can do this legally:
void Method() {
{
int decl;
}
{
int decl;
}
}
because neither variable is in the parent scope of the other.
