Maybe that was a poor example, since I picked something which is one line either way.
How about this message signature:
Twilio::PhoneNumbers.buy_a_number!(options) #returns the new number or raises an error
I have this implemented in the bowels of Appointment Reminder, because back in the day Twilio did not ship that functionality with the API. The "snippet" to do it requires about 30 lines. They're also probably the wrong 30 lines, because e.g. if Internet gremlins bushwhack one of the HTTP requests, it dies uncleanly. I'd have been mighty obliged if it was one line which worked atomically. (It is, to my understanding, now that there exists a decent first-party Twilio library. I recall showing that method on a slide at Twilio HQ one day while begging for that first party library to get created.)
