Comments

Zolo has three comment forms: // runs to the end of the line; /* … */ comments a block (no nesting); /// is a documentation comment, surfaced by the LSP and zolo doc:

A line comment, a block comment, and a /// documentation comment.

Playground

// Feature: Comments
// Syntax: `//` (line), `/* ... */` (block), `///` (doc)
// When to use: inline documentation, suppressing code, LSP doc.

// Line comment — runs to end of line.
let x = 42  // inline also works

/*
   Block comment. Can span multiple lines.
   Does not nest (an inner `/*` closes the outer block
   at the first `*/`).
*/

/// Doc comment — shows up on LSP hover and in
/// `zolo doc`. Use on fns, structs, enums, traits.
fn double(n: int) -> int {
  return n * 2
}

print(double(x))
