Examples: (add-invisible-fns binary-+ unary-- foo) (add-invisible-fns + unary-- foo)Each of the events above makes unary functions
unary-- and foo
``invisible'' for the purposes of applying permutative :rewrite
rules to binary-+ trees. Thus, arg and (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-fn is a function symbol and the unary-fni are 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.
