I guess that makes sense. For the list monad, "select" would make sense as a name for "map" (list fmap), and "select many" would make sense for "mapcat" (list bind).

> It's just that if you provide "bind" and "unit" (called "select many" and "select" in LINQ, I think)

LINQ's Select is actually fmap.

Peter,

Thanks for the new post. The tests are doctests http://docs.python.org/library/doctest.html although I prefer to use the Nose testrunner http://code.google.com/p/python-nose/ to collect and run tests - just run "nosetests" (or, without the setup.cfg, "nosetests --with-doctest") to see that the test passes. Not that important, just allowed me to keep the stdout-based feel of your examples without a more elaborate TestCase setup. (And of course, shortly after my second comment I realized the answer was in the question. "No output" indeed.)

I also particularly like a) this refactoring style of teaching a programming idea and b) to see refactorings through the lens of a version controlled repo.

Thanks again, I'll take some time to go through the runnable code soon.

Luke,

Sorry, I usually make a runnable version of the code, but I ended up splitting into two articles (I just published the latest one). My last post is the runnable version of both put together. I hope it helps.

Feel free to take the code, fix it up, improve it, post it somewhere, etc.

I looked into your repo. I don't know how your test harness works exactly. It seems weird that the tests are just comments. But, I added the event firing code directly to main.py and ran main.py and got the correct output.

(I didn't look long, but am confused why I could not get:

click = Event()

dlclick = click >> value_filter_r("left") >> doublize_r(
.01,
lambda l1, l2 : "double left"
)

to still pass the original test with the final code. No output.

I stuck this progression in a bitbucket mercurial repository here: http://bitbucket.org/loppear/rx-python/ I hope that's alright with you. A fun exercise and a fun video to copy&paste to.
