I used pip to install into Python 3.4 (32-bit) from PyPI. It fetched 
"recordclass-0.4.3.tar.gz" and compiled it instead of fetching 
"recordclass-0.4.3-cp34-cp34m-win32.whl".

Why?

Come to think of it, what's that "cp34m" in the name? I don't have that 
in the regex module's wheels, I have "none" instead.

Rename "recordclass-0.4.3-cp34-cp34m-win32.whl" to 
"recordclass-0.4.3-cp34-name-win32.whl".

With the new name, it installs and seems to work!
