def zork(up)

  puts 'foo'

  up.call(42)

  puts 'bar'

end

up = Proc.new do |n|

  return if n == 42

  puts 'foo'

end

zork(up)

#>>> foo

#>>> ... unexpected return (LocalJumpError)



def zork

  puts 'foo'

  up = Proc.new do |n|

    return if n == 42

    puts 'foo'

  end

  bla = up.call(42)

  puts 'bar'

end

zork

puts "baz"

#>>> foo

#>>> baz



def zork

  up = lambda do |n|

    return if n == 42

    puts 'foo'

  end

  bla = up.call(42)

  puts 'bar'
