> Calls take positional arguments only (design §3.2 rule 13, §17.21); name: value exists only inside attribute arguments.

An error from the `parse` phase. `sakura explain V0014` prints this explanation offline.

Calls take positional arguments only (design §3.2 rule 13, §17.21); `name: value` exists only
inside attribute arguments. Pass the value positionally, or pass a record when the call needs
an options bag.

Wrong:

```sakura
clamp(x, lo: 0, hi: 10)
```

Fixed:

```sakura
clamp(x, 0, 10)
```

## Wrong program [#wrong-program]

[`compiler/tests/ui/V0014_named_argument.sakura`](https://github.com/icantcodefyi/sakuralang/blob/master/compiler/tests/ui/V0014_named_argument.sakura), which the compiler's ui suite runs through `sakura check`:

```sakura
fn double(n: Int) -> Int { n * 2 }

fn four() -> Int { double(n: 2) }
```

`sakura check --json` reports this record (pretty-printed; `$DIR` is the fixture's directory):

## Fixed program [#fixed-program]

[`compiler/tests/ui/V0014_named_argument.fixed.sakura`](https://github.com/icantcodefyi/sakuralang/blob/master/compiler/tests/ui/V0014_named_argument.fixed.sakura), which `sakura check` accepts with no diagnostics:

```sakura
fn double(n: Int) -> Int { n * 2 }

fn four() -> Int { double(2) }
```
