From: "fxn (Xavier Noria) via ruby-core" Date: 2023-06-22T06:23:38+00:00 Subject: [ruby-core:113993] [Ruby master Feature#19742] Introduce `Module#anonymous?` Issue #19742 has been updated by fxn (Xavier Noria). Yeah, we do not see it the same way. Anonymous to me means you don't have a name. If the module has a name, done, it is not anonymous. If you have a _temporary_ name, in particular you have a name. To be honest, I would leave modules anonymous until they are assigned to a constant in a non-anonymous module. That is, I'd only have two states, anonymous, and non-anonymous: ```ruby m = Module.new m.name # => nil m::C = Class.new m::C.name # => nil, in my ideal design, not real A::B = m::C m::C.name # => "A::B", this does work this way ``` but this cannot be changed even if we agreed, only sharing for the discussion :). ---------------------------------------- Feature #19742: Introduce `Module#anonymous?` https://bugs.ruby-lang.org/issues/19742#change-103651 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- As a follow-on , I'd like propose we introduce `Module#anonymous?`. In some situations, like logging/formatting, serialisation/deserialization, debugging or meta-programming, we might like to know if a class is a proper constant or not. However, this brings about some other issues which might need to be discussed. After assigning a constant, then removing it, the internal state of Ruby still believes that the class name is permanent, even thought it's no longer true. e.g. ``` m = Module.new m.anonymous? # true M = m m.anonyomous # false Object.send(:remove_const, :M) M # uninitialized constant M (NameError) m.anonymous? # false ``` Because RCLASS data structure is not updated after the constant is removed, internally the state still has a "permanent class name". I want to use this proposal to discuss this issue and whether there is anything we should do about such behaviour (or even if it's desirable).
