Yeah, I see the problem -- putting test scripts in a test directory is
not a full solution; what about interactive sessions? And while it's
good practice to put test scripts in a test directory, I don't want to
*force* people to do that.

Oops. This is handled properly on installation, since build/lib and
build/platlib are merged at that point. I've been wondering for a while
why I decided always to build pure Python modules to build/lib, and
extensions to build/platlib. You have discovered a very good reason
*not* to do so: it breaks the idea of the build tree as a
pseudo-installation for testing purposes.

I see a couple of solutions: first, put all modules in either build/lib
or build/platlib, i.e. do the merge at build-time rather than
install-time. Second, have some sort of "build in-place" option that
lets developers, well, build in-place. That is, .py files in the source
tree wouldn't be touched (they're already in-place!), and extension
modules would be put into the source tree. (I still favour putting
compiler turds in build/temp.plat -- anyone foresee problems with that?)
I'm still struggling with the Right Way to install modules, so I won't
be able to work on fixing the build stuff right away. Keep bugging me
