PEP 824 proposes adding two new operators to Python: the None-coalescing operator (??) and None-coalescing assignment operator (??=). These operators provide a concise way to handle None values similar to operators found in TypeScript, JavaScript, C#, Dart, and other modern languages, reducing verbose conditional checks and improving code readability.
Tilia is a new Haskell code formatter that addresses three long-standing challenges: comment handling, operator fixity inference, and CPP support. The formatter uses a principled approach that integrates with GHC and Cabal to discover operator fixities from installed dependencies and source code, handling complex scenarios like re-exports and data constructor imports.
