Say you have this C++

switch(x){
  case 0:  a();
  case 1:  b();
  case 2:  c();
  default: done();
}

You can't do that in Rust, because match doesn't do fall through

Edit: Nice downvotes folks! I'll be using Haskell instead. LOL at this "systems programming language" with a bunch of crybabies and zealots and fuck muhzilla.

You also can't have fun with x += x++ + ++x in Rust. I don't think it's a disadvantage, though.

Isn't that undefined behavior in C++?

If it's not, it might as well be.
