/**
Provides the ability to verify key paths at compile time.
If "keyPath" does not exist, a compile-time error will be generated.
Example:
// Verifies "isFinished" exists on "operation".
NSString *key = SQKeyPath(operation, isFinished);
// Verifies "isFinished" exists on self.

Greetings, NSHipsters!

As we prepare to increment our NSDateComponents -year by 1, it's time once again for NSHipster end-of-the-year Reader Submissions! Last year, we got some mind-blowing tips and tricks. With the release of iOS 7 & Mavericks, and a year's worth of new developments in the Objective-C ecosystem, there should be a ton of new stuff to write up for this year.

Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Here are a few examples of the kind of things I'd like to see:

  • Using NSStringFromSelector(@selector()) as a safer way to do KVC / KVO / NSCoding.
  • Panic's [rather surprising discovery about the internals of the Lightning Digital AV Adapter](http://www.panic.com/blog/the-lightning-di

I'm writing in response to events that have recently come to light involving a sexual assault at a tech conference. Background information can be found [here][1], [here][2], and [here][3] as well as on twitter and google.

I've been watching this from the sidelines, and I've been wrestling with several questions that I can't seem to shake and that I really don't have answers to.

I wear many hats, both in the tech community and others. I'm a coder, a speaker, a user group organizer, a conference organizer, and even a boss. Each of those roles colors how I see this, but there's one role that is overpowering in my reaction.

See, I'm a Dad. A dad of two beautiful and innocent girls who are 3 and 2. They have their whole lives in front of them and so the questions I'm struggling with are:

; Comments start with semicolons.

; The clojure reader assumes that the first thing is a
