# SIFR-PARSE-0006: Invalid call argument order or unpacking syntax.

> Invalid call argument order or unpacking syntax.

`SIFR-PARSE-0006` belongs to the **Parsing** diagnostic family. It means: invalid call argument order or unpacking syntax.

## Why It Happens

The parser cannot recover a supported Sifr syntax tree from the source. Fix syntax before type, ownership, or package analysis can continue.

<Info>
  Use `sifr --explain SIFR-PARSE-0006` locally to see the renderer's exact message template and any machine-applicable suggestions for the compiler version you are running.
</Info>

## Erroneous Code

```python theme={null}
def main( -> int:
    return 1
```

## How To Fix It

Fix the source syntax first. Parser diagnostics happen before Sifr can reason about types, ownership, or package structure.

## Fixed Code

```python theme={null}
def main() -> int:
    return 1
```
