True.  In my quick tour of debuggers over the past week, I've often read
"Unfortunately this only works from the command-line," many times
(here's one: http://www.linuxjournal.com/article/7876).  How is that

As Alex says, Lisp is the ultimate debugger anyway --- Lisp systems had
debuggers before Python, Ruby et al even existed.  Where do you think
they got the idea?  Lisp machines had source debuggers for the entire
operating system, and Emacs works on the same principle, with
interactive debuggers available.

Saying that a language is incomplete without an interactive debugger is
a little misleading: I've gotten a lot of use out of Scheme over the
past two years, and have only started using "real debuggers" (i.e. not
the REPL) in the past two weeks.
