Curried predicate functions

[asinghvi17]

Basically defining e.g. GO.intersects(x) = Base.Fix1(GO.intersects, x). Turns out to be quite useful when performing dataframe ops.

I wouldn't mind taking a shot at this, do you do an assignee system? Also just the usual PR?

[asinghvi17]

No particular assignee system I think, but a regular PR would be fine - I'll hold off from implementing this then. Great to see people interested in the project!

Thanks! No need for a system at this stage, probably whoever is free will review your PR pretty quickly.

You can also make a draft PR and ask questions at that stage too if there are any problems.

[luntan-maker]

Thank you for the warm welcome! I went ahead and made a PR, I look forward working with you.
