def import_methods: (Module module, *Module extra_modules) -> self

Imports methods from modules. Unlike Module#include, Refinement#import_methods copies methods and adds them into the refinement, so the refinement is activated in the imported methods.

Note that due to method copying, only methods defined in Ruby code can be imported.

module StrUtils
  def indent(level)
    ' ' * level + self
  end
end

module M
  refine String do
    import_methods StrUtils
  end
end

using M
"foo".indent(3)
#=> "   foo"

module M
  refine String do
    import_methods Enumerable
    # Can't import method which is not defined with Ruby code: Enumerable#drop
  end
end
