* Add Report.debug * Implement function call scoping * Implement variable scoping - Rename `Identifier::scope` to `calling_scope`, and concatenate the identifier scope into `name` if necessary. - Track current scope in SemanticAnalyzer, similar to UserFunctionVisitor. - Use current scope in SemanticAnalyzer when visiting identifiers. * Update grammar for `::identifier` global scoping * Introduce ScopableName for function resolution * Address review comments - Check for display_debugs missing * Add ScopableName for identifier resolution * Some cleanup - Remove `Identifier::calling_scope`, as it is tracked in the semantic analyzer - Refactor `ScopeName::exists` to `global` for better clarification of its use - Removed `X::maybe_scoped_string/name` * Address self-review comments * Rename `Function::module_name` to `scope`
