@Red-Portal thanks for this! I've had a look at the code itself and all seems fine.

Before merging, would you be able to:

• make a patch release in Project.toml
• add a changelog entry in HISTORY.md?

[Red-Portal]

Done!

@penelopeysm I don't have merge rights so someone will have to press a button!

[penelopeysm]

Oh, I'm sorry! I actually checked and I thought that you'd have merge rights since you're a member of the TuringLang organisation. I guess it might be because it's a merge into main.

[penelopeysm]

I triggered a release, so you should be able to use it in a short while.
