Examples: (add-invisible-fns binary-+ unary-- foo) (add-invisible-fns + unary-- foo)Each of the events above makes unary functions
foo``invisible'' for the purposes of applying permutative
(unary-- arg)will be given the same weight and will be permuted so as to be adjacent.
General Form: (add-invisible-fns top-fn unary-fn1 ... unary-fnk)where
top-fnis a function symbol and the
unary-fniare unary function symbols, or more generally, these are all macro aliases for function symbols (see macro-aliases-table).
For more information see invisible-fns-table. Also see set-invisible-fns-table, which explains how to set the entire table in a single event, and see remove-invisible-fns.
