Hi, get confused intern-soft return a symbol which already unbound, 

Here are the lines to make a symbol then makunbound the symbol, but after that the intern-soft still return the symbol:

(setq a-test-variable-unbound-later t)

(intern-soft "a-test-variable-unbound-later")

(makunbound 'a-test-variable-unbound-later)

(boundp 'a-test-variable-unbound-later)

(intern-soft "a-test-variable-unbound-later") ;; why not nil?

It's a feature or a bug? Thanks

If you want to know whether a symbol is bound as a variable use
'foundp', not 'intern-soft'.

Done.
