As requested on gitter.

LGTM, but would need accompanying doc in README.md. @wsargent, what do you think?

"colonoscope" really?

[som-snytt]

I'll update it to "Colonus", as in Oedipus blind and near death.

I'll also revise the test to I ❤️ 👵, 👀 like 🤕

keeping it family friendly aids enterprise uptake

and who is the poster child for "family friendly" if not Oedipus?

[som-snytt]

Cleaned it up.

[SethTisue]

👀 LGTM, but still needs doc 📖 in README.md 😛

I don't mind going the distance. Thanks again for your attention to detail and keeping me from doing something embarrassing. Any remaining embarrassments are, of course, my own.

I'll create an issue to support e"\:" instead of double colon; I was too lazy, and StringContext doesn't make it trivial. I considered catching InvalidEscapeException and fixing escaped colon that way. That would be embarrassing, but maybe less than e"::".

The other desirable feature would be to handle emoticons, e":)". That was too much for a weekday and might require a SIP or something.
