What is MAML?

MAML is a minimal, human-readable data format. Think JSON, but cleaner:

{
  project: "MAML"
  tags: [
    "minimal"
    "readable"
  ]

  # Comments are supported
  spec: {
    version: 1
    author: "Anton Medvedev"
  }

  notes: """
Raw multiline strings.
No escaping needed.
"""
}

Key differences from JSON:

• # comments
• Unquoted keys
• Optional commas (newlines work as separators)
• Raw multiline strings with """
• No trailing comma errors
