Syntax for tuple-like enum variants

The readme says the syntax for something like

```rust
enum Color {
Hsl(u8, u8, u8)
}
```

is

```
"Hsl"(0, 100, 200)
```

However, shouldn't it be this?

```
"Hsl"([0, 100, 200])
```

because it's supposed to be `"tag"(data)` and a bare sequence of values is not valid data in Eon.

Now, you might say that `"Hsl"(0, 100, 200)` is a special syntax for tuple-like enum variants, but

1. Why does this in particular get a special syntax?
2. Isn't `"Hsl"([0, 100, 200])` valid syntax anyway, meaning that there are two ways to express the same thing?
