Conversation
Add `p1 || p2 || p3` syntax for matching multiple alternatives in a single match arm. Supports combining any pattern types: literals, type patterns, and nested patterns. - Add `OrPattern` CST node kind and parsing - Add `Pattern::Or` AST variant and parsing - Handle `OrPattern` in HIR lowering - Handle `Pattern::Or` in evaluator (first matching alternative wins) - Format or-patterns correctly in the formatter - Add integration tests for or-pattern matching - Document or-patterns in pattern_matching.md
