I'm going to regret this joke, but: I posit the difference lies in how much cache you need.

well done.

If only my wife's body was immutable.

I'd love to continue this but I have garbage collection to attend to.

And they say nobody around here has a sense of humor! Happy to see it was just a matter of injecting the proper dependencies!

Whoops, came to reddit by accident.

I think you want a mutable wife. Otherwise you'll eventually have to throw her out and get a new one.

The compiler will optimize that.

Guys, please keep this stuff on /r/programming. The signal to noise ratio on HN is already bad enough.
