Re: Proposal for containers: Add 'pop' function to Data.Map

Or lookupRemove? Or possibly lookupAndRemove? The name pop will be confusing in Data.Sequence. On Sun, Dec 6, 2020, 12:17 PM Carter Schonwald wrote:

LookupThenRemove seems like a more descriptive name. Though I guess I can see why pop has appeal.

I suggest you add a version for Data.Sequence combining lookup with deleteAt. I wanted that for something fairly recently.

Yeah, Python's `pop` made me call it `pop`. I had hoped to find other examples, but Java, Rust, and Ruby don't seem to offer `pop`-like functions for their (hash)maps.

The name pop makes me think of a stack. Is this use of the word common? Python uses that name, which is why I'm familiar with it:
