Edit Question
Title
Body
I have a few classes which do nothing except in their constructors/destructors. Here's an example class BusyCursor { private: Cursor oldCursor_; public: BusyCursor() { oldCursor_ = CurrentCursor(); SetCursor(BUSY_CURSOR); } ~BusyCursor() { SetCursor(oldCursor_); } } // example of use void DoSlowThing { BusyCursor busy; ... do something time-consuming ... } I'm a little concerned about future readability. Am I being too "tricksy" here, with a variable ("busy") which is never actually used in the code? Could some static analysis tool suggest they be removed, or is this idiom sufficiently common not to worry about?
