Python: The import system. Why can't I easily import a file from any location in the file system?
Javascript: Lacks support for 64-bit integers and arbitrary-precision decimals.
SQL: SQL injection.

I believe all of these three should give me os.path.isdir:
import os
import os.path
import os.path.isdir
os.path.isdir(...)
from os.path import isdir
import os.path.isdir as isdir
Sometimes, for some reason if I only import a module, I can't use submodules. So `import os` wouldn't give `os.path.isdir`. I don't know when that occurs, maybe it was in an ancient version of python. But it leaves me with an uneasy feeling every time I use a submodule. Anyone know when this happens?
Last but not least, it should be easier to import stuff from above the script. If my script lives at ./tools/foobar.py, and I want to import ./helper.py, it should just be something like
# ./tools/foobar.py
from .. import helper
$ python ./tools/foobar.py # simple run-a-script syntax
$ python -m tools/foobar # hideous run-a-module syntax
# ./tools/foobar.py
# hideous boilerplate header
import sys, os
SCRIPTDIR = os.path.relpath(os.path.dirname(__file__) or ".")
PARENTDIR = os.path.relpath(os.path.join(SCRIPTDIR, ".."))
sys.path.insert(0, PARENTDIR)
import helper
$ python ./tools/foobar.py # simple run-a-script syntax- Hardcoded recursion limit + no tail call optimization. I understand Guido's reasons for this but I find myself writing ugly code instead of beatiful code. (But maybe changing this would make Python's internals ugly.)
Mainly Python but other languages too. - Length of the collection: len(foo). String representation: str(foo). Why not foo.len() or foo.str(). Or even better: foo.len or foo.str. As a Python user, I'm not a fan of getters. I think we should use the "attribute syntax" to get data about and of the object/type/thing, regardless if it involves any computations or not. (but would probably generate more problems than solve little nitpicks)

As for tail-call optimization, here's Guido's opinion (which I agree): http://neopythonic.blogspot.pt/2009/04/tail-recursion-elimin...
