Was the unary + operator only included for symmetry with the unary - operator, or does it find some practical use in C++ code?
Searching h
A bit late, but here's a very twisted use that I stumbled across. Apparently the + operator can be useful (if perhaps not strictly necessary) when designing safeguards around the possibility of encountering empty preprocessor tokens. See this post for a more in-depth discussion.
It's practical, but by no means pleasant.
