Like defun, but creates a memoized function.
Also, if the name is a CONS, then the first element is the name, and the rest
is a list of keyword arguments, TABLE and NORMALIZATION as per MEMOIZE.
Memoize the function associated to given SYMBOL.
Beware that unless the function was declared NOTINLINE, callers may have inlined
the original definition and will not see the memoized function.
Moreover, if the function is self-recursive,
this declaration must have happened before it was defined.
Keyword argument TABLE (default: a fresh EQUAL hash-table) lets you
specify an existing hash-table for the memoized computations;
it may have been created with appropriate options regarding equality predicate
and weak pointers, initial contents, etc., and you may clear it when needed.
Keyword argument ARGUMENT-NORMALIZER (default: NIL) lets you specify a function
taking a list of arguments and returning a normalized list of arguments,
so that all lists with the same normalization will share the same memoized
computation. NIL means no such normalization, which is the same as #’LIST.
Keyword argument CALL-NORMALIZER (alias: NORMALIZATION, default: NIL)
lets you specify a function taking a continuation and the function arguments,
e.g. with lambda-list (CONTINUATION &REST ARGUMENTS)
which may transform the argument list before to call the continuation
with a normalized argument list that will be used to query the computation cache
and invoke the actual computation function; NIL means no such transformation,
which has the same effect as specifying #’APPLY as a transformation.
If the function was already being memoized, any previous memoization arguments, i.e. TABLE and ARGUMENT-NORMALIZER, is replaced with the newly specified values (unspecified arguments are replaced by defaults rather than left as previously specified).
Given a function, return a memoizing version of same function. Keyword arguments TABLE and NORMALIZATION are as per MEMOIZE.
undoing the memoizing function, return the memoization-info record for the function
Forget the memoized result of calling SYMBOL with arguments ARGUMENTS. Do not forget memoized results of calling the function with other arguments. Returns T if a stored result was found and removed, NIL otherwise.
