The reason is simple: I have this long, almost 60-lines function, with
three levels of lambdas nested. (I'm using request.el, and I have to
make two requests sequentially, so I have a callback inside a callback.
I could probably use deferred or something, this is one of the ideas.)
It's just pretty complicated, and changing anything in this code is
a headache. Also, edebugging is simpler with separate instrumentable
defuns.
Best,
