This is the exact behavior I would expect. I think of auto as
"this variable is going to be the same type as that variable."
Since in is const int, then j also is going to be const int. If
you want to copy n into a nonconst variable, you have to cast
away the const.
int j = cast( int )n;
auto j = cast( int )n;
+1
This works fine for pods, no cast required
int j = n; ++j;
...and this does what one would expect too
struct S {
int* value;
}
void funky(const S s) {
int* s1 = s.value;
*s1 = 5;
}
