Cool, thanks for the answer. These restrictions seem somewhat complex.
They are required. Otherwise we would end up with a C++-like situation
where copies end up happening too frequently.
This wasn't very intuitive for me, so just throwing this out (feel free
to ignore if it has already been discussed :-) )
From a language design perspective, maybe it would be more intuitive to
have different syntaxes for copy and move, like:
There used to be a unary move operator. This was a huge pain.
match move x {
Some(move y) => foo(move z);
}
And so on. I don't want to go back to that world.
