Programming tastes evolve over time. At one point, and for at least a few years, I believed Python was the one true language revealed mystically to GVR. Up until that point, I'd done most programming in C++, so you can imagine how much fun Python was, in comparison. After further development and discovery of other programming languages, the shortcomings of Python have become obnoxious, much like torturing someone by dripping water on their forehead incessantly. Part of the problem is that I have to use Python for my professional work now. Using a language for your day job is a sure way to reveal all the issues.

Here's what rubs me raw day-in and day-out:

1. Lack of immutable/persistent data structures. 2. Lack of multi-line anonymous functions/lambda. 3. Variable scoping fail, causing hacks like the new `nonlocal` keyword. 4. worst_possible_variable_name_convention. 5. Python evangelism. (community issue, mostly) 6. Hypocritical "explicit is better" and "flat over nested" values with insane amounts of magic built into language and class system. 7. No switch. 8. GIL. (Actually the CPython runtime in general) 9. No macros. 10. the insane way "unicode" is supported. 11. and on and on...

At this point I write Python code, but not generally by choice. Mostly my coworkers can't even imagine writing code in another language, given that we have been allowed to choose our implementation language(s) as a team.
