Oh man, list comprehensions, that's me. I get inspired, caught up in the flow, write some eldritch horror of a LC. 30 seconds later "What in the name of saint Lovecraft does this even do?" (sighs) Rewrite as a loop. I mean, I guess they are fine in small doses, very small doses, But boy do they read poorly compared to the rest of Python.
I also need something to save me from my regexps, the verbose flag helps a lot. but what would be really nice is some sort of python subset that could compile to the state machine. I would also like composable expressions, that is, composable at the graph level not the string composition we are forced to use. And a pony, I would also like a pony.
As you can tell I am not a fan of APL, not because of what it can do but because of the super compressed syntax it adopts. see also: perl
