Automatically read and write bytecode Importing or executing a Hy file now loads the byte-compiled version if it exists and is up to date, and if not, the source is byte-compiled after it's parsed. This change can speed up Hy a lot. Here are some examples comparing run times of the current master (491b474e) to this commit, on my laptop with Python 3.6: - `nosetests --exclude='test_bin'` goes from 3.8 s to 0.7 s (a 5-fold speedup) - `hy -c '(print "hello world")` goes from 0.47 s to 0.20 s (a 2-fold speedup) - Rogue TV's startup goes from 3.6 s to 0.4 s (a 9-fold speedup) Accompanying changes include: - `setup.py` now creates and installs bytecode for `hy.core`, `hy.contrib`, and `hy.extra`. - The `hyc` command under Python 3 now creates bytecode in `__pycache__`, as usual for Python 3, instead of putting the `.pyc` right next to the source file like Python 2 does. I've removed a test of `hy.extra.anaphoric.a-if` that triggers #1268 when the test file is byte-compiled and then hits some weird `macroexpand` bug or something when I try to work around that—Nose crashes when trying to produce an error message, and I can't seem to replicate the bug without Nose. 2017-04-10 02:27:51 +02:00			`(defmacro m []`
