Description

So decorators have very strict syntax, while in reality, any valid python expression can be used when decorating. See github's highlighting below too.

* **Editor name and version**: Sublime Text 4152
* **Platform**: MacOSX
* **Color scheme**: Custom, but any
* **MagicPython version**: v.1.1.1
* **A sreenshot**:
* ![](https://gcdnb.pbrd.co/images/7XuUK9SyomCG.png?o=1)
* **5-10 lines of surrounding code**:
```python
class A:
@D[C][prtl]
def a(self):
pass

@a | b | c
def a(self):
pass
```

Research direction

Start by reproducing the two decorator examples in Sublime Text with MagicPython v1.1.1 and compare their highlighting with GitHub's result. Then locate the decorator syntax-highlighting entry point in the repository and identify the existing tests for decorators, if any. Done means both valid expressions are highlighted as decorators without syntax errors.
