Excluding a builtin name from __all__ sounds like a perfectly sensible

But then, a tool that looks into __all__ to find for example what
objects to document will miss open. I’d put open in __all__.
"import *" would then override the builtin open. A good reason not to
use "import *" I guess, but also a good reason not to create names that
shadow builtins.
Heh. Instead have fun with io.ioopen(), gzip.gzipopen(),
webbrowser.webbrowseropen(), etc.? We do have namespace support for a reason.
Or urllib2.urlopen, oh wait - that's real...
If I was importing from those namespaces I probably *would* import and
rename to have unambiguous names (and you would *have* to if there was
any possibility of you using the builtin open). io.open is arguably an
exception to this as it does the same as the builtin open...
Using meaningful names is *good*. This is a reason I dislike modules
that just call their base exception class "Error". You *have* to use it
from the namespace (or import with import as and give it a good name)
for it to have any meaning.
