Same for me. I don't see why it needs to be obscure, if we can use
symbolic names instead of numbers.
After all, we making these interfaces for humans, not for machine.

We have different positions on that with Eliot:
Eliot  adding new numbers by extending existing interface (to access
the system attributes).
While i think that it would be better to have primitives with
corresponding names, which explaining what attribute value it
returns and what it serves for.

IMO, saving developer's time is much better than saving few bytes in
VM binary (because of using numbers instead of name).
