I've lost count now of how many times I've had to downgrade to 
auto despite always wanting immutable or const. This doesn't work:

  auto reg = regex(`(foo)`);
  const match = "foo".matchAll(reg);
  writeln(match.captures); //oops, captures isn't const

It should, but it doesn't. Maxime talked about it here as well:
