Ammm... although with the general attitude I do agree, this one sentence
is wrong: the compiler does coalesce strings, and thus
116 /tmp> cat q.m
#import <Foundation/Foundation.h>
int main() {
NSString *s=@"test";
if (s==@"test") printf("Oops!\n");
return 0;
}
117 /tmp> cc -Wall -framework Foundation q.m && ./a.out
Oops!
118 /tmp>
