No, I wrote a macro like `cl-loop` here:

https://github.com/okamsn/loopy

I received a bug report that said that the above function would raise an 
error after running a second time here:

https://github.com/okamsn/loopy/issues/17

For some reason, the value returned by `symbol-function` changes after 
the function is invoked the first time. Just using the macro itself does 
not signal an error.
