Good, glad you can take it the right way :) Learning is not by doing
whatever you like and being told "Oh yes, very good job" like in
kindergarten. Learning is by doing something (or proposing doing
something) and getting solid feedback. Of course, that feedback may be
wrong - your idea might be brilliant even though I believe it's a bad
one - and you need to know when to stick to your guns and drive your
idea forward through the hail of oncoming ... okay, this metaphor's
getting a bit tangled in its own limbs... okay, the meta-metaphor is
getting... alright I'm stopping now.

Was here on python-list:

https://mail.python.org/pipermail/python-list/2014-January/664617.html
https://mail.python.org/pipermail/python-list/2014-January/thread.html#664617

The thread rambled a bit, but if you like reading, there's some good
content in there. You'll see some example code from my Pike MUD
client, Gypsum, and Steven D'Aprano and I discuss it. If you'd rather
skip most of the thread and just go to the bits I'm talking about,
here's my explanation of the Pike code:

https://mail.python.org/pipermail/python-list/2014-January/665286.html

And here's Steven's take on it:

https://mail.python.org/pipermail/python-list/2014-January/665356.html

And keep reading from there. TL;DR: It's not perfect as a DSL, but
it's jolly good as something that is already there and takes no
effort.
