Comment:
You can always use the dictionary notation to avoid any coercions:
{{{
sage: p = MixedIntegerLinearProgram(solver='ppl')
sage: p({1:2})
2 x_1
}}}
Of course that is highly inconvenient. The backends just need a method
`base_ring()`, say, that returns the base ring that the backend wants. But
all backends need to be changed for that, obviously. Let's do this on
another ticket, I've opened #13650 for this. How about you review #13646
and I'll write a patch in #13650 on top of this ticket.
