The number one reason against pass-by-const-reference here is not
technical: it looks funny, it is (I think it's safe to say) at best
pointless, and nobody else is doing it.
Would you make this statement if 'int' were replaced with 'Foo', where
Foo is a class or struct?
No. Note the "here" in "reason against pass-by-const-reference here".
It refers to "const int&" in the example code above.
The original poster stated from the start that he was talking about
types like int, bool and so on. He, you, I and probably everyone else
agree that passing e.g. a std::string by const reference is a good
thing.
