It would help in cleaning up our code if you underlined unreferenced local variables. It would be especially nice if you could do that for variables which are classes as well as those which are simple types like int and float.
Since not all compilers do warn you about unreferenced local variables (VS .NET 2002/2003 does, Intel C++ 7.1 never did on my system), I'd really love to see such a feature in Visual Assist X!
Just because while compiling, it is already too late (they don't hurt much, but I like my code as clean as possible)...
yes, i always try to remove them, since they only confuse you when you return to the code months later. you spend time trying to work out what the variable is for, only to find that it isnt for anything *shrug*
