Quote of the Week

This time, we have two quotes for the price of one:

The borrow checker breaks you down so that it can build you back up, stronger and more resilient than you once were. It also had me do all sorts of weird things like catch flies with chopsticks and scrub counters to a polish.

I always think of borrowck as an angel sitting on your shoulder, advising you not to sin against the rules of ownership and borrowing, so your design will be obvious and your code simple and fast.

– llogiq on /r/rust

Thanks to Christopher Durham for the suggestion!

Please submit your quotes for next week!
