This is pretty straightforward procedural code, imo. Perhaps I'm
misunderstanding what you're wanting?


def function_a
  puts 'a was run'
end

def function_b
  puts 'b was run'
end

logged_in = false

# using 3 because 0..2 iterates over [0, 1, 2]
# but we don't actually care about the values
3.times do
  function_a unless logged_in
  logged_in = true
  function_b
end

# >> a was run
# >> b was run
# >> b was run
# >> b was run
