Interning Symbols

Interning Symbols

[Nordlöw]

Is it possible to intern a symbol and make it have a property whose
value is a references to a another object like we do with setf()?

If I want to copy a symbol along with all its 4 components into
another obarray do I have to manually copy (using get and set) the
value, function def and property-list?

Do you mean, does this work:

(setq my-obarray (make-vector 1021 0))

(setf (get (intern "foo" my-obarray) 'some-property)
       (evaluates-to-some-object))

I don't know why it wouldn't:

(require 'cl)
(macroexpand (quote ...)) =>

(let* ((--cl-var-- (intern "foo" my-obarray))) (put --cl-var-- (quote 
some-property) (evaluates-to-some-object)))
