Once, long ago, coincidentally a few people were asking the same question: how do I get a method object of a class?

Answers to the question would depend on particular circumstances of the code where this functionality is needed. One would be about using MOP methods like .^lookup, the other is to use method name and indirect resolution on invocant: self."$method-name"(...). Both are the most useful, in my view. But sometimes declaring a method as our can be helpful too:

class Foo {
    our method bar {}
say Foo::<&bar>.raku;

Just don’t forget that this way we always get the method of class Foo, even if a subclass overrides method bar.
