Re: continuation passing in Emacs vs. JUST-THIS-ONE

[Karthik Chikmagalur]

One of the issues I've faced with using generator.el and its offshoots,
such as the emacs-aio library (written by Chris Wellons), is that I can't
run `debug-on-entry' on or edebug an `iter-defun'.  This makes it
difficult for me to write iterator-based logic for anything non-trivial.

Is there some way to step through calls to iterators?

What needs to be fixed in generator.el for this?
