PR #1428: API Documentation for Standard Library Modules

My first open-source contribution to Quantinuum’s Guppy has been merged!

PR #1428 might not look flashy on the surface — it’s documentation — but getting it right taught me more than I expected.

The task was straightforward: add module-level docstrings to Guppy’s standard library. Without them, IDE tooltips are blank and auto-generated docs have nothing to work with. The modules covered include guppylang.std.futures, guppylang.std.collections, guppylang.std.option, and the qsystem family — which handles operations on actual Quantinuum quantum hardware.

What made it interesting was the review process. Two maintainers pushed back on my wording in ways that sharpened my understanding of the project:

• “Module” vs “library” — guppylang.std is referred to as the standard library, not a module. Small distinction, but it matters for consistency across docs.
• “quantum system operations” vs “Quantinuum Systems device operations” — the latter is more precise. These aren’t generic quantum ops; they’re specific to Quantinuum hardware.

It’s a good reminder that documentation isn’t just writing — it’s understanding the thing well enough to describe it accurately.

Thanks to the maintainers at Quantinuum for the thorough review feedback throughout the process.
