Note that pybench is written in a way that it can handle ImportErrors
and SyntaxErrors gracefully. This is per design, since test modules can
well be written for more recent Python versions that support a certain
features or syntax not present in earlier versions.

In the above case, it may be a good idea to redirect pickle to
the new Strings3 module (see my other message). Likewise, the
Strings test module should redirect to the new Bytes test module
in Python3.

The Unicode and Strings modules should not be loaded in Python3.
Instead, the Bytes and Strings3 modules should be used. This can
be changed in Setup.py of pybench.
