regression on enums with type parameters

Not sure when this started happening, but it used to work ~2 years ago.

**Input file**
```haxe
enum Foo<Child> {
	Bar<T>(options : Array<T>);
}
```

**Broken output**
```haxe
enum Foo<Child> {
	Bar<T>
	(options : Array<T>);
}

```

**Expected output**
No change.
