Tidies generate_lazy_export.rs:

  • Introduce local FIRST_TOP_LEVEL_STMT_IDX constant for the magic 1 stmt index.
  • Replace the (ModuleIdx, ExportsKind, bool) tuple with a LazyModuleInfo struct.
  • Convert the two early-return guards into a filter_map(Module::as_normal_mut).filter(...) pipeline.
  • Extract the duplicated "take first expression statement and wrap" block into replace_first_expr_stmt driven by a LazyExportWrap enum.
  • Drop the always-identical StmtInfoIdx parameter from update_module_default_export_info.
