prefer `if let` to match with `None => {}` arm in some places

2016-07-03T23:27:02+00:00

This is a spiritual succesor to #34268/8531d581, in which we replaced a number of matches of None to the unit value with `if let` conditionals where it was judged that this made for clearer/simpler code (as would be recommended by Manishearth/rust-clippy's `single_match` lint). The same rationale applies to matches of None to the empty block.

Disallow `derive` on items with type macros

Rollup merge of #34436 - jseyfried:no_block_expr, r=eddyb

2016-06-26T02:20:14+00:00

To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list. Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions. For example, ```rust macro_rules! make_stmt { () => { let x = 0; } } fn f() { make_stmt! {} //< This is OK... let x = 0; //< ... unless this line is commented out. } ``` Fixes #34418.
