(Version indicator: 2019 Nov 01) The halloweenmath package originated from a question asked for enjoyment on TeX-LaTeX Stack Exchange by the user cfr (see ); it defines a handful of commands for typesetting mathematical symbols of various kinds, ranging from "large" operators to extensible arrow-like relations and growing arrow-like math accents, that all draw from the classic Halloween-related iconography (pumpkins, witches, ghosts, cats, and so on) while being, at the same time, seamlessly integrated within the rest of the mathematics produced by (AmS-)LaTeX.
