There was a problem hiding this comment.
New AST variants were created and nobody bothered to include them here and probably nobody will in the future. It is then better to just test allowed expressions.

Looks good to me. Thanks! @bors r+ |

[RFC-2011] Expand more expressions cc rust-lang#44838 Expands `if`, `let`, `match` and also makes `generic_assert_internals` an allowed feature when using `assert!`. `#![feature(generic_assert)]` is still needed to activate everything. ```rust #![feature(generic_assert)] fn fun(a: Option<i32>, b: Option<i32>, c: Option<i32>) { assert!( if a.is_some() { 1 } else { 2 } == 3 && if let Some(elem) = b { elem == 4 } else { false } && match c { Some(_) => true, None => false } ); } fn main() { fun(Some(1), None, Some(2)); } // Assertion failed: assert!( // if a.is_some() { 1 } else { 2 } == 3 // && if let Some(elem) = b { elem == 4 } else { false } // && match c { Some(_) => true, None => false } // ); // // With captures: // a = Some(1) // b = None // c = Some(2) ```
