• Ensure readability and consistent code formatting.
• Provide a single "true" formatting style, with no configuration required, making it easy to adopt across teams.
• Guarantee idempotence: formatting the code multiple times yields the same result after the first application.
• Properly handle comments and merge blank lines.

#Status

• Parenthesis inference
• Expression layout composition
• Expression formatting
• Top-level declaration formatting
• Comment formatting
• Blank line awareness
• Fully test coverage

test {
  let code =
    #|/// Tree data structure

    #|
    #|/// Greet a person
    #|pub fn hello(name:String)->Unit{ let str = "hello, \{name}!"; println(str) } 
  let result = @formatter.format(code)
  println(result)
  inspect(
    result,
    content=(
