You just discard all references to an object.
And then afterwards I called (makea), creating a new 'a object. But
then why does it throw an exception when I deref it?
I searched the archives and learned that my intended coding style
(using global vars) isn't idiomatic:
Hi all,
i stumbled upon this code, and am curious why it's not working:
user (defn makea []
(def a 232))
#'user/makea
user (makea)
#'user/a
user a
232
user (ns-unmap *ns* 'a)
nil
user (makea)
#'user/a
user a
