多个instance_of？

Question

我如何Object#instance_of?接受多个参数,以便下面的例子可以工作？

class Foo; end
class Bar; end
class Baz; end

my_foo = Foo.new
my_bar = Bar.new
my_baz = Baz.new

my_foo.instance_of?(Foo, Bar) # => true
my_bar.instance_of?(Foo, Bar) # => true
my_baz.instance_of?(Foo, Bar) # => false

Answer 1

[Foo,Bar].any? {|klass| my_foo.instance_of? klass}
