But it says that for your example:
void f(void)
{
int x; #1
if (int x = 1) #2
{
}
}
#2 is local to the if statement, so it doesn't collide with #1.
3.3.2p4 says that #2 is local to the if statement, and 6.4p3 says that #2 goes
out of scope when the if statement finishes.
Are you suggesting that we handle these requirements for #2 without entering a
new scope ?
