We want this, because:

  • Specializing for indexing by int and by slice are different and should be treated differently
  • It avoids creating the temporary slice object.
  • Indexing by slice is syntactically distinct from indexing by object. The compiler can generate better code if it has different instructions.

For full discussion see faster-cpython/ideas#319
