Yes, modules are atoms and the only way to know if an atom is actually a module during development is if you check if there is a .beam file on disk. If you want a quick check if something is a module, then you can use is_atom. There is no way we can provide a performant is_module for development. In production, if you do releases, then this check is faster since modules are loaded upfront. *José Valimwww.plataformatec.com.br <http://www.plataformatec.com.br/>Founder and Director of R&D* On Mon, Feb 26, 2018 at 12:56 AM, <[email protected]> wrote: > I've found that in practice both `Code.ensure_loaded` and > `Code.ensure_compiled?` are both extremely slow in practice.
