9.5.1 Exceptions
There are two exceptions to rules governing Shorthand transformations:
- Symbol forms comprised entirely of characters in the Emacs Lisp symbol constituent class (see Table of Syntax Classes) are not transformed. For example, it's possible to use
-or/=as shorthand prefixes, but that won't shadow the arithmetic functions of those names. - Symbol forms whose names start with '
#_' are not transformed.
