Even though `Generator::current()` can return `null` once generator is
exhausted, `foreach()` never iterates after iterator ends, so we can
safely remove `null` (unless, of course, generator can yield `null`).
Check if this type was defined via a dockblock or type hint otherwise the inferred type should always match the assigned type, and we don't even need to do additional checks
There is an issue with constants over a certain length where additional values are added to fallback_params in the assigned_type but not in const_storage_type which causes a false flag for this error to appear. Usually happens with arrays/lists.
Added two separate tests to cover both lists, and arrays to ensure this issue is fixed.
Apply suggestions from code review.
