Previously, attributes on 'if' expressions (e.g. #[attr] if true {})
were disallowed during parsing. This made it impossible for macros to
perform any custom handling of such attributes (e.g. stripping them
away), since a compilation error would be emitted before they ever had a
chance to run.
This PR permits attributes on 'if' expressions ('if-attrs' from here on).
Both built-in attributes (e.g. `#[allow]`, `#[cfg]`) are supported.
We still do *not* accept attributes on 'other parts' of an if-else
chain. That is, the following code snippet still fails to parse:
```rust
if true {} #[attr] else if false {} else #[attr] if false {} #[attr]
else {}
```
Introduce `#![feature(half_open_range_patterns)]`.2020-01-10T06:29:04+00:00Mazdak Farrokhzadtwingoow@gmail.com2019-12-11T09:04:34+00:00urn:sha1:d5598aa7a07b324789576585f4f035c93993fea4
This feature adds `X..`, `..X`, and `..=X` patterns.
