For discussion, see thread starting at:
https://lists.gnu.org/archive/html/emacs-devel/2019-04/msg00316.html
* doc/lispref/customize.texi (Composite Types): Do not overspecify
:match-alternatives predicates.
* doc/lispref/eval.texi (Intro Eval): Anchor definition of "side
effect" for cross-referencing...
* doc/lispref/functions.texi (What Is a Function): ...from here.
Define what a pure function is.
* doc/lispref/internals.texi (Writing Emacs Primitives): Describe
currently preferred approach to marking primitives as pure and
side-effect-free.
* doc/lispref/symbols.texi (Standard Properties): Expand description
of pure and side-effect-free properties.
