Let’ say you need to debug this piece of code:

very_cool_method(egg, sausage)

What would you do? I guess something along the lines of:

spam = very_cool_method(egg, sausage)
p spam

Well, Ruby 1.9 let you do something cooler instead:

very_cool_method(egg, sausage).tap{ |s| p s }

The cool thing about tap is that you can use it to eavesdrop method chains:

very_cool_method(egg, sausage).tap{ |s| p s }.now_make_sandwich_from(bacon)

Hooray!

Hey
Mom, Dad, this is Ryan.
Oh so this is the famous boy we’ve been hearing so much about.
Nice to finally meet you Mrs. L33T. And sir.
So, Ryan, what Warcraft server do you play on?
Is that on umm is that on the computer? Oh you know what, i think i forgot the desert in the car.
Who do you think you are bringing his kind into my house!?
But dad, he’s a nice guy, really.
No he’s a n00b Jessica, a n00b!
But ryan and I are perfect together.
This relationship is headed for an epic fail, young lady. You’re a L33T damn it, we don’t date n00bs, we pwn them!!
Well maybe I don’t want to be a L33T!
Your insolence, for the lose!
No, maybe I looove that he watches VHS tapes still. And maybe i love that his phone still has a cord.
You might as well date someone who plays Aliance.
I date whoever I want!
Over my level 80 rogue’s temporary dead body!
Mr. L33T, I may run around in circles when I play halo, and I might never get a monster kill, well, I can’t even find the space bar half the time. But I know when I find true love, and that is worth more than all the uber gear in the world.
Too long, did not listen!
