A revert wasn't requested by the individual who raised the concern (or,
indeed, explicitly by *anyone*..  it was hinted at, but I felt the
individuals who were hinting at it were leaving it up to that individual
who had a concern), and I discussed it with him extensively and we came
to what I believe is an understanding.  I'm not sure that I understand
the need to bring it up again, unless you have a concern regarding what
was committed.

I agree that I jumped the gun on it and said as much.  On the flip side,
it's not had quite a bit of review and there is a promise of more, which
I feel is great for the project as a whole.

I find this to be an interesting argument considering most of our
documentation doesn't include real-world examples.  I'm happy to add
more examples than those listed thus far, certainly, though I've
understood documentation to be of less general importance than code
quality and maintainability- and someone willing and committed to
maintain it.

This wouldn't be the only case of documentation (indeed, *any*
documentation) being added after a commit, and so I'm mystified by this
requirement for *real-world* examples in documentation to be provided
prior to commit.

Simon, if you want me to revert it because of an objection over the
design, code quality, maintainability, or utter lack of documentation,
then I absolutely respect that request and would be happy to do so.

This request I am completely lost on.
Thanks,
