That's a bug - 'vector' should specialize the default 'erase' (and, most
probable, 'insert') implementation (which requires 'push_front', which
'vector' doesn't support) to use 'push_back' (or may be provide a
'push_front' - it's doable). I'll look into it on the weekend.

That's not a bug - 'list' does not support 'push_back', because it's not
possible to implement it in the way that would satisfy the algorithm's
complexity requirements - see and

FWIW, 'copy_if' + 'push_back' is equivalent to 'copy_backward_if' +
