Most of these are old, but some specific messages for specific tests:
* trait-contravariant-self.rs: failed due to a soundess hole:
05e3248a79
* process-detatch: 15966c3c1f
says "this test is being ignored until signals are implemented" That's
not happening for a long time, and when it is, we'll write tests for
it.
* deep-vector{,2}.rs: "too big for our poor macro infrastructure", and has
been ignored over a year.
* borrowck-nested-calls.rs's FIXME #6268 was closed in favor of
rust-lang/rfcs#811
* issue-15167.rs works properly now
* issue-9737.rs works properly now
* match-var-hygiene.rs works properly now
Addresses a chunk of #3965
macro_rules! is like an item that defines a macro. Other items don't have a
trailing semicolon, or use a paren-delimited body.
If there's an argument for matching the invocation syntax, e.g. parentheses for
an expr macro, then I think that applies more strongly to the *inner*
delimiters on the LHS, wrapping the individual argument patterns.
This makes edge cases in which the `Iterator` trait was not in scope
and/or `Option` or its variants were not in scope work properly.
This breaks code that looks like:
struct MyStruct { ... }
impl MyStruct {
fn next(&mut self) -> Option<int> { ... }
}
for x in MyStruct { ... } { ... }
Change ad-hoc `next` methods like the above to implementations of the
`Iterator` trait. For example:
impl Iterator<int> for MyStruct {
fn next(&mut self) -> Option<int> { ... }
}
Closes#15392.
