Lazy Imports -- I Like This Idea

So Python 3.15 will introduce a new, “lazy” import mechanism
<https://peps.python.org/pep-0810/>.

So far I have done one script where I moved an import into the
function where it was used, instead of doing it globally; this reduced
the script startup time from around 1.5 seconds down to about a
quarter second.

“Lazy” imports would avoid the need for such workarounds, while
keeping all imports together so they can be found more easily.
