-- MOL Calculator

fn add(a, b)
  return a + b
end

fn multiply(a, b)
  return a * b
end

fn square(x)
  return x ^ 2
end

-- Use pipes to chain calculations
let result be 5 |> square |> to_text
show "5 squared = " + result

-- Multi-step pipeline
let answer be 3
  |> add(7)
  |> multiply(2)
  |> square

show "((3 + 7) * 2)² = " + to_text(answer)

5 squared = 25

-- Data processing with MOL

let names be ["Alice", "Bob", "Charlie", "Diana"]
let scores be [85, 92, 78, 95]

-- Find the highest scorer
let best be max(scores)
show "Highest score: " + to_text(best)

-- Process and display
for i in range(len(names)) do
  let name be names[i]
  let score be scores[i]
  show name + ": " + to_text(score)
end

-- Sort and show
let sorted_scores be sort(scores)
show "Sorted: " + to_text(sorted_scores)

-- Create a thought with confidence
let idea be Thought("Machine learning transforms healthcare", 0.87)
show idea
show "Confidence: " + to_text(idea.confidence)

-- Create a memory
let mem be Memory("research", idea)
show mem

-- Guard the quality
guard idea.confidence > 0.7 : "Idea needs more evidence"
show "Idea is solid!"

-- The MOL way: pipe data through transformations

fn format_name(name)
  return name |> trim |> upper
end

fn greet(name)
  return "Hello, " + name + "!"
end

let message be "  mounesh  "
  |> format_name
  |> greet

show message
-- Output: Hello, MOUNESH!
