Just so that you know that such cases exist, I am in a position where
I have access to systems with (distro-supplied) Python installed. I
can use anything supplied with Python (i.e., the stdlib - and
__preview__ would fall into this category as well). And yet I have
essentially no means of gaining access to any 3rd party modules,
whether they are packaged by the distro or obtained from PyPI. (And
"build your own" isn't an option in many cases, if only because a C
compiler may well not be available!) This is essentially due to
corporate inertia and bogged down "do-nothing" policies rather than
due dilligence or supportability concerns. But it is a reality for me
(and many others, I suspect).
Having said this, of course, the same corporate inertia means that
Python 3.3 is a pipe-dream for me in those environments for many years
yet. So ignoring them may be reasonable.
Just some facts to consider :-)
Paul.
