I’d like to talk here about two not-so-new features of C++ (auto types and lambda functions) that managed to bite me recently, even though I thought I knew them well enough (I still do!).
According to me, it doesn’t show that one should ditch them into oblivion and never use them (but some people make their life easier by doing so), but clearly that they should be handled with care, as they more or less act as syntactic sugar on C++ type system, which can be, unfortunately, both overly rigid (which is why we use them in the first place) and overly flexible (which is usually why bugs get in our way).
Let’s get to the point.
