**What it does**
Checks for implicit calls to possibly unbound methods.
Checks for implicit calls to possibly missing methods.
**Why is this bad?**
Expressions such as `x[y]` and `x * y` call methods
under the hood (`__getitem__` and `__mul__` respectively).
Calling an unbound method will raise an `AttributeError` at runtime.
Calling a missing method will raise an `AttributeError` at runtime.
