Remove .all import of infinity

[mkoeppe]

... throughout the Sage library.

sage.rings is becoming a namespace package in the course of modularization (#29705), so we are replacing imports from sage.rings.all throughout the Sage library.

The failure in src/sage/rings/integer.pyx is not from this ticket.

What is the new policy? Do we intend to remove all all.py eventually? If not, what should(can) remain in all.py? Or this is determined by how we split sage library? The last case is not good, I think...

Or there won't be no change in all.py but we stop importing things from it in Sage library?

comment:8

All all.py are kept, for the purpose of populating the global interactive environment (sage.all).

We are just getting rid of imports from sage.PAC.KAGE.all within the Sage library. In particular, the imports from those packages sage.PAC.KAGE that become namespace packages, i.e., filled with modules from several distributions.

I am asking because you keep lines like

from sage.rings.all import AA, QQbar, CC
