It's only a light worry as there are plenty people who make that
mistake in 2.x by leaving off the keys() entirely. And I hardly think
this light worry is worth changing the behavior that was decided on

map(encode_step, sys.argv[1:]). Of course the problem with
the encode_step is unless it is a no-op on Windows, it can break
filenames as badly as decoding them will on unix, unless the common OS
interfaces all reverse the process (in which case doing it manually is
never necessary).

I also hope that, if the "recommended" encoding uses a heuristic on
the file's contents, the file has enough data in the encoding to make
a good guess. Music metadata rarely is that. :)

od trade.
As for callable() vs addable(), etc., the reason is obvious. Function
calls very commonly have large side effects and are only rarely
idempotent. The operations you mention are expected to have no side
effects on the object. This makes a try/except much more palatable for
addition,

If something like that sounds reasonable for usage, I'll start looking
into how it looks for implementation. (Probably a big ball of mud! And
sounds like it depends on the python-side interface to the ast
easons) without having to
shoehorn its own syntax into the language.
There's a lot of holes to this story, including at least how these
