Projects I have worked on that use this guideline have suffered from
subtle errors anyways. As the name with and without the underscore
resemble each other too much, these errors tend to go unnoticed,
especially if the names are next to operators, e.g. "foo_->bar".

I personally avoid shadowing by selecting noticeably different names
(usually abbreviations or synonyms) for function arguments.
