Context default values and side-effects

[zachriggle]

The context module tries to be helpful in setting sane default values for some settings based on other settings. Unfortunately these are incomplete, and have potentially unwanted side-effects.

Side-Effects

>>> from pwn import *
>>> context.word_size = 1337
>>> context.arch = 'i386'
>>> assert 1337 == context.word_size
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

Incomplete

There's no way to set a default endianness. For example, PowerPC is generally big-endian, but setting arch="powerpc" does not set this.
