dynamic method definition in ruby

wtf.rb

class MyClass
  def static_yield(*)
    yield if block_given?
  end
  
  define_method :dynamic_yield do |*|
    yield if block_given?
  end
  
  define_method :dynamic_yield_fix do |*, &block|
    block&.call
  end
end

MyClass.new.static_yield      { puts "Now you see me!" }    # => Now you see me!
MyClass.new.dynamic_yield     { puts "Now you don't!" }     # => nil ಠ_ಠ
MyClass.new.dynamic_yield_fix { puts "This works though." } # => This works though.
