Bug #21538: initialize_dup not called when duping class/module
https://bugs.ruby-lang.org/issues/21538#change-114460
* Author: chucke (Tiago Cardoso)
* Status: Open
* ruby -v: 3.4.5
* Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN
----------------------------------------
Not sure whether this is expected behaviour or not, but just leaving it here to start the debate on whether callbacks like `initialize_dup` are supposed to be called when a module or class is duped (the same happens with `initialize_copy` and `initialize_clone` btw):
class A
def initialize_dup(_)
puts "dup instance"
super
end
def self.initialize_dup(_)
puts "dup class"
super
end
end
A.new.dup #=> "dup instance"
A.dup #=> nothing
