instance method

Module#>

(::Module other) -> bool?
mod > other → true, false, or nil

Returns true if mod is an ancestor of other. Returns false if mod is the same as other or mod is a descendant of other. Returns nil if there’s no relationship between the two. (Think of the relationship in terms of the class definition: “class A < B” implies “B > A”.)
