[Python-ideas] working on a PEP for the __preview__ package

[Matt Joiner]

Just a suggestion:

Golang uses an "exp" namespace, this would translate to a exp package
for grouping like modules in a similar way that xml, http and
concurrent are currently used.
http://golang.org/pkg/exp/

The name is unoffensive, and somewhat more palatable than __preview__,
which really isn't a protocol, or a bag for special interpreter
switches like __future__.

Under this scheme, the currently proposed modules would be:

exp.regex
exp.daemon
exp.ipaddr

Rather than

__preview__.regex
__preview__.daemon
__preview__.ipaddr

Either way I really look forward to something for PEP 3153 being trialed.
