I know that if I have a variable with a function name, I can call it using
funcall, like this
(setq func-ref 'my-func) (funcall func-ref)
I am wondering if there's a similar functionality for variables (defined with
defvar), so that I can set
var-ref like this
(setq var-ref 'my-var)
and use it to get the value of
my-var and/or update it.
EDIT: I want to use this functionality in a function which takes as argument a reference to a variable that will be changed in the function.
