There was a problem hiding this comment.
This can be simplified:
#[test]
fn magic_deref() {
struct Wrapped<T>(T);
let s = "hello";
if_chain! {
then { Wrapped(s) }
else { Wrapped(&s) }
};
}|

There was a problem hiding this comment.
This as well:
#[test]
fn no_move() {
struct NoCopy;
let x = NoCopy;
if_chain! {
then { drop(x); }
else { drop(x); }
}
}

My now-closed-by-me MR #14 seemed simple and passed the in-tree
if_chaintests but produced a number of regressions in projects of my own. That seems suboptimal. I have distilled the failure cases into these new tests, which pass on currentif_chainand break with my #14.
