Although i understand the reasoning behind using the leading
underscore, the Python devs should have realized that anyone
who follows Pythonic convention [1] will ignore a symbol
that starts with an underscore . So if the intention is that
`_source` should be a part of the public API, then
obviously, defining it in "standardized private form" is
very unwise. 

But to answer your question, no, none of my code relies on
the `_source` attribute. So i really don't care what happens
to it.

[1] Which i would hope is a rather large group, and not just
another "Rick singleton".
