There's also an option of pattern matching any struct, not exactly a guard, but
changing your code a bit shouldn't be a problem
```
def foo(%_{} = _struct), do...
def foo(map) when is_map(map), do...
```

Also note that there's is_map_key/2 guard that serves the same purpose when
used as `is_map_key(arg, :__struct__)`, allowing only maps but not
structures:
