Debugging works well enough, but code search is very simplistic
(brings a lot of false positives, because it's basically dumb text
search, not sensitive enough to the language), and refactoring doesn't
work at all, because we have no facilities for that.  For small
projects, you could use 'A' or 'Q' in Dired, but that quickly becomes
unworkable in large projects.
