Convenience function that mirrors <code><a href="https://purrr.tidyverse.org/reference/pluck.html">purrr::pluck()</a></code>.

Provides utilities to create and use lenses to simplify data
manipulation. Lenses are composable getter/setter pairs that provide a
functional approach to manipulating deeply nested data structures, e.g.,
elements within list columns in data frames. The implementation is based on
the earlier 'lenses' R package <https://github.com/cfhammill/lenses>,
which was inspired by the Haskell 'lens' package by Kmett (2012)
<https://github.com/ekmett/lens>, one of the most widely referenced
implementations of lenses. For additional background and history on the
theory of lenses, see the 'lens' package wiki:
<https://github.com/ekmett/lens/wiki/History-of-Lenses>.
