This commit introduces fundamental changes to Myc's language structure to enhance type safety and scoping clarity. Key changes include: - Introducing local scopes for `do` blocks. - Separating statements (`def`, `assign`) from expressions, where statements now have no return value and are only allowed within blocks. - A block now consists of multiple statements followed by a single final expression. - Stricter validation rules are enforced, such as disallowing redefinition of local symbols in the same scope while allowing shadowing of outer symbols. - Compiler errors are generated for statements used in expression contexts. The implementation involved modifications to the AST, parser, binder (scope-stack), and various compiler passes, along with VM runtime optimizations.
