Python 3.15 is expected to speed up some programs and simplifies handling immutable data. UTF-8 as standard requires testing.

Python programs are set to get faster startup times with PEP 810 "Explicit lazy imports," which allows scripts to defer loading imported libraries until they're actually needed rather than at startup.

Python 3.15 is out with explicit lazy imports, UTF-8 as the default encoding, frozendict and sentinel types, the Tachyon ...

Importing modules in Python is ubiquitous; most Python programs start with at least a few import statements. But the performance impact of those imports can be large—and may be entirely wasted effort ...

Or, on the assumption that you're willing to do work to support lazy loading, you move all of the global code bar imports into the init function, and then have the last line of your module be init().
