It can also be a "special form" (e.g. what you have in (symbol-function
'if)), or a keymap, or a symbol (alias) or a vector or string (kdb
macro).

Of course, it can also be any other kind of value, tho in that case
it'll only be useful if the symbol is treated in an ad-hoc manner
elsewhere, since "normal" use (such as evaluating something of the form
`(SYMBOL ...) or adding SYMBOL as the command to use in a keymap) would
then lead to an error.
