# Grouping instructions in blocks

[Syntax and values](README.md)

A block is a group of instructions that belong together. Indentation shows which instructions belong to a decision, loop, or function.

Compound statements end their header with `:` and place a non-empty body on
later indented lines:

```text
if ready:
    say "Go!"
```

Inline bodies are invalid:

```text
if ready: say "Go!"  # invalid
```

A comment does not count as a statement, so a comment-only block is invalid.
Pliro has no `pass` statement.
