> You can of course try to extend the use of lazy_import and see if you
can get it to work for things like NN as well.
I would certainly like to try that. It would be a pity if rings (like
`NN`) are fundamentally incompatible with `lazy_import`. Consider `arb`
for example: it makes sense to define a global `RBF` (for real ball
field), analogous to `RR`. It also makes a lot of sense to lazily import
this: it's unlikely to be commonly used, it would save an import of at
least 2 Python modules and it would save the loading of the external
library `libarb`.
