pluck :: Accessible a => TypeRep b -> String -> Array a -> Array (Maybe b)

In its infancy Sanctuary was a companion to Ramda, focused on providing safe versions of unsafe Ramda functions. Sanctuary is now close to being a Ramda alternative, and provides many more functions than it once did. It’s important to occasionally remove poorly defined and/or unnecessary functions so the library becomes more coherent over time, even as it grows.

pluck provides a slightly more succinct way to express a composition of map and get:

> S.pluck(Number, 'x', [{x: 1}, {x: 2}, {x: '3'}, {x: null}, {}])
[Just(1), Just(2), Nothing(), Nothing(), Nothing()]

> R.map(S.get(Number, 'x'), [{x: 1}, {x: 2}, {x: '3'}, {x: null}, {}])
[Just(1), Just(2), Nothing(), Nothing(), Nothing()]

I have several issues with pluck:

• it doesn’t provide much of a readability improvement over map + get;
• we provide a shorthand for map + get but not for map + gets;
• we provide a shorthand for map + get but not for map + prop; and
• type representatives are a complex concept best referenced in as few places as possible.

If you’re okay with pluck being removed from the library, vote 👎; if you would like the function to stay, vote 👍. If in addition to keeping pluck you think we should add plucks as shorthand for map + gets, please say so. Thanks. 😃

I do think map + prop is a more common combination than map + get, so I am open to the idea of changing pluck rather than removing it.

I like the idea of changing to map + prop. I can do the PR if that’s how we decide to go.
