I have bunch of code that goes like :

This is begging for a RAII solution where I pass var as template parameter but
would require default constructor. This is an actual problem I have right now as
all save/restore are harder and harder to keep in sync for no reason and
generate a lot of boilerplate.
This is a problem I have right now that default constructor would solve, and
this isn't the first time I hit that need.
oldVar isn't being default constructed in your example, nor can I see why you'd
need a default constructor in order to use RAII for save/restore.
