Debugger skips local variables if they have the same name as a function from core

[bbatsov]

While working on my slides for tomorrow's CIDER talk I noticed that when I instrument this:

defn fibo-iter
  ([n] (fibo-iter 0 1 n))
  ([curr next n]
   (cond
     (zero? n) curr
     :else (recur next (+ curr next) (dec n))))

stepping passes over the first argument of recur (next).

Actually, I don't think it's about the recur.

That's probably because your variable has the name of a core function.
The debugger avoids displaying the value of stuff from core otherwise it would be much noisier.

It's still a bug (the debugger has enough information to know that that's a local var), but you should be able to avoid it by just changing the name.

This was actually my second suspicion. :-) OK, I'll use some other name from the presentation as a workaround.

@Malabarba didn't you recently fix this?

[Malabarba]

I did. Not sure why I didn't tag the issue.
