It's nice to wipe out these extra hints if it won't take too many steps. The AST shows,
```
`-PseudoObjectExpr 'void'
  |- (Syntactic) BinaryOperator
  `- (Semantic) CXXMemberCallExpr 'void'
```
I wonder if it is possible to enumerate all the bad cases we don't want (e.g. Don't walk down the expression if we encounter a `BinaryOperator` in `PseudoObjectExpr`.)
