<pre>For C primers, it would be useful to warn on `a < b < c`:
int main(int argc, char* argv[])
{
int a = 2;
int b = 3;
int c = 4;
if (a < b < c) {
/* ... */
}
}
I think it makes sense to warn on these codes
as the compiler emits warnings on codes like `if (a = b)`.
P.S. gcc emits warnings on such codes.</pre>
