The choice seems to be between
* non-mathematical order
* no order (undefined in Python2, raise in Python3)
I don't really have a strong opinion on which to use here.
One advantage of having an order is that you can speed up algorithms by
working with ordered collections.

Thats because relocate-once.py partially wor
If you re-package the existing binary then you should

* then run relocate-once.py (or just start sage)
* when successful, relocate-once.py deletes itself

Where is the problem, I did that before and it works just fine.
Of course sage isn't on py
As William already said, there is the github<->trac bot. Even without that,
you can just copy branches over. So if you want to do the review on github
and then stick it into trac thats easy to do.
But if you want to use the github issue tracker then that wouldn't work as

1) don't cdef class attributes, it just makes debugging unnecessary hard.
Unless you are wrapping C-level types where you can't avoid it, of course.
Just keep it in python, maybe use cpdef if you must.
2) I'd recommend using __cinit__ instead of __init__ with cdef classes and
use more of a RAII

I would argue the opposite, making local accounts is exactly what you
usually do to let users run their own programs

Another argument against a public method name is that e is implemented as
exp(1) and not as a named constant under the hood:
sage: e.is_constant()
False
sage: pi.is_constant()
True
