Combinators that are thought to be at least situationally useful, mostly for
tacit (or point-free) programming. "To Mock a Mockingbird" refers to the book
"To Mock a Mockingbird and Other Logic Puzzles: Including an Amazing Adventure
in Combinatory Logic", by Raymond Smullyan (which the author of this module
hasn't actually read). See
http://www.angelfire.com/tx4/cus/combinator/birds.html and
https://hackage.haskell.org/package/data-aviary-0.4.0/docs/Data-Aviary-Birds.html
an (incomplete?) list of birds introduced.
Blackbird, as named in "To Mock a Mockingbird". This is like

(https://youtu.be/seVSlKazsNk).
Phoenix, according to Data.Aviary.
