ERROR: cannot add methods to a builtin function
Why can’t I do that? And is there a way to dispatch based on the defined <: function in a polymorphic way?
Thanks
Is there a question?
Sorry, i posted early by mistake. Added the question.
No, you cannot change the way subtyping works. Doing so would break everything. You can make your own generic function that calls <: and can be modified over that but dispatch will not use it.

Given your previous question about overriding =, I am curious what problem you are trying to solve. Maybe there is a simpler way to get what you want?
