# Comma: separators and trailing commas

[Syntax and values](README.md)

## Behavior and details

Commas separate call arguments, function parameters, List items, and Map entries. Trailing commas are accepted in these lists and command-call arguments. Commas are not a decimal separator in source, even in Dutch syntax. A comma cannot join independent statements or create a tuple.

## Example

```pliro
# language: en
function add(a, b,):
    return a + b
say(add(2, 3,), 1.5,)
```
