That wouldn't help, because in the `GCallback cb = &some_function;` case, I guess you want to highlight both `cb` and `some_function` -- or none.  They are both callable, but there's no syntactic way to know it, short of figuring out `GCallback` is a function type -- and even then, only `cb` really is a callable, the RHS should be but what if the author was nasty…
```C
  const char *p = "hello";
  void(*cb)(void) = p;
```

This will compile just fine -- even more so if you'd explicitly casted `p` appropriately --, but `p` isn't a callable.


PS: BTW, GitHub highlighting is confused by function pointer type apparently, and highlights `void` as a function call.
