The slow startup from imports is my biggest annoyance with python.<p>We had a decent sized library at a previous company that pulled in modules that defined huge register maps, wrapped c++ libraries, etc.<p>I wrapped all imports in a lazy importer that was triggered by the first attribute access. It brought our script startup times from 3 seconds down to a fraction.<p>Blows me away that this isn&#x27;t default behavior for ALL modules.
