A couple of other data points:

- Swift has nonzeroBitCount: https://developer.apple.com/documentation/swift/int/2886050-nonzerobitcount

- Rust has count_ones: https://doc.rust-lang.org/std/primitive.u64.html

- Go's math/bits package has OnesCount

- The closest thing in Mathematica appears to be DigitCount, which isn't base-specific.

@Mark Shannon: what name would you suggest, and why? The term "population count" feels too non-obvious and specialist to me, and anything involving "Hamming" likewise.

"count_ones" isn't obviously a bit operation.

"count_set_bits"?
