I believe Emanuel is alluding to the memoization pattern “if a
computation (e.g. of the set of all displayable characters) is too
expensive to perform every time its result is needed, cache the result
in some storage that survives between the times it is needed (e.g. a
data file in .emacs.d/var/)”.
