That was easy to try, "pip install recordclass", but it failed:

C:\Programs\Coding\Anaconda3\Scripts>pip install recordclass
You are using pip version 7.0.3, however version 9.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade
pip' comm
and.

Looks like lack of Visual C++ tripped me up again.

Strange how Python code can't install with purely Python code. I don't
plan to have Visual anything on Linux either.

It might be possible to do something with 

lib\recordclass\test\test_record.py ->
build\lib.win32-3.4\recordclass\test and 

lib\recordclass\record.py -> build\lib.win32-3.4\recordclass, 

but I wouldn't know what.

Maybe I should go back to Python 2.7.8 for this.
