Good catch.

It's suitable for one function pointer-like alias in typedef. But it will provides wrong fix for `typedef char (&refArray)[2], (*ptrArray)[2];`, i will see if that's easy to fix:
```
# | -  typedef char (&refArray)[2], (*ptrArray)[2];
# | +  using refArray = char (&)[2];
# | +using ptrArray = char (&refArray)[2], (*)[2];
```
