Show HN: Jevlang: Python with a Smart "If"
Jevlang adds a smart `if` to Python via the `~` operator and `jev`/`case` blocks, backed by TypeSafe's hosted classifier Jev - files are rewritten to plain Python at import, and each `~` is a paid API call returning probabilities (fires at >= 0.5) or labels. Questions typed as strings (yes/no), lists (scale), or dicts (options) enable thresholding (`> 0.8`), ranking, and branching; install with `pip install jevlang`, set `TYPESAFE_API_KEY`, and use the skill via `claude plugin marketplace add sumanmichael/jevlang` or `npx skills add sumanmichael/jevlang`. Requires Python 3.10+, and `.py` files shadow `.jev` files so the import hook never hijacks existing modules.

score
score 8 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
