os.fdopen() calls unbuffered. I presume that it's enough if we can
make all three of them (for stdin, stdout, and stderr) unbuffered and
don't need to specify different buffer sizes per file -- that would
complicate the interface more than I care for.
Apparently the traceback object doesn't contains the right linenumber
when -O is used. Rather than guessing whether -O is on or off, use
tb_lineno() unconditionally.
When completing a simple identifier, it completes keywords, built-ins
and globals in __main__; when completing NAME.NAME..., it evaluates
(!) the expression up to the last dot and completes its attributes.
It's very cool to do "import string" type "string.", hit the
completion key (twice), and see the list of names defined by the
string module!
Tip: to use the tab key as the completion key, call
readline.parse_and_bind("tab: complete")
- Don't use "from copy_reg import *".
- Use cls.__module__ instead of calling whichobject(cls, cls.__name__);
also try __module__ in whichmodule(), just in case.
- After calling save_reduce(), add the object to the memo.
