I recently wrote a tool that worked on bodies of text in Rust. Had multiple instances of

    if let Some(body) = ...

I'm working on a game engine in Rust in my spare time, I'll probably end up with that same code in the physics side.

You know that you could use Some(body)

...once told me...

Damn it, I can hear it in my head!

oh god, it won't stop playing in my head. I know there's a pause button somewhere. reaches for hammer see you in a few hours. thwack

Can someone explain this, please?

At the risk of being a serious weirdo and way overexplaining: gladly!

An earworm[1] is a (part of a) song that gets stuck in your head.

The GP was wondering if "gimmie gimmie gimmie"[2] was the fewest bytes required to put one in someone's head.

I shaved 12 bytes off by using All-Star[3] by Smash Mouth. It was a very popular song in its day, it's newer than ABBA, and lately it's become a meme[4] of its own[5], partly on the back of being featured in Shrek. It's even the basis for a trilogy[6] of mash-up[7] albums[8].

Hash collision.

    Somebody (somebody) ooh somebody (somebody) 
    Can anybody find me .... somebody to love?

That's why I used casing to differentiate

It is a reference to a song by Smash Mouth:
