Crate & Quote of the Week

This week's Crate of the Week is alias by Huon W. Thanks go to Reddit user notriddle for the suggestion. Submit your suggestions for next week!

alias allows mutably aliasing values – which seems to actually be safe, somewhat surprisingly. Honestly, I'm a bit shocked about it myself.

— llogiq on the alias crate.

Submit your quotes for next week!
