🐍 Python 3.15: Lazy Imports Without Hiding Them Inside Functions

The interesting part? Your imports can stay at the top of the file.

In 2023, I wrote that I wanted more than autocomplete: a tool that could inspect files, make edits, run tests, read the errors and try again.

Two things since then make that wish look less hypothetical. And they raise a question I care about more than the demos.

🔐 Git: Force-Push With a Lease, Not a Crowbar

You rebased your feature branch. Git refuses your push because history diverged. So you type git push --force, close your eyes and hope.

If a teammate pushed to that branch in the meantime, their commit is gone. Git has a politer option.

⚡ Beyond autocomplete

AI autocomplete is cool. Asking a chatbot to explain a regular expression is useful. Getting a quick example of an unfamiliar API saves me a search.
