 making coroutine copy-able would require to copy the stack. this is
 dangerous even with POD.
 you get unexpected behaviour if you copy a stack which has
 references/pointers to objects on the stack.

 int i = 0;
 int * j = & i;

 If you copy the stack above, j of the new (copied-to) stack would contain
 the address of i of the original (copied-from) stack.
