imported, causing more confusion.
I personally would weigh these so as to prefer (2). The option of installing
your own version when the standard version doesn't exist seems reasonable;
there may be reasons that you can't or don't want to install the distribution's
version.
I also agree that (2) is the better option. General Python philosophy seems to
be to not prohibit actions unless there is a *really* good reason (i.e.
sum()ing strings), and option (1) would require installing third-party modules
into the stdlib to workaround the prohibition.
