Hello;
Many times when I write some module, I add local symbols, then later I might
change the code and those symbols will no longer be used.
For example
f[x_]:=Module[{a,b},... a=...; ....]
Suppose that 'a' is still used, but 'b' is not used inside the module. Both
will be colored green as things are now.
It would be nice, if a new color is made for symbols that are local, but NOT
used, i.e not referenced.
This way, after some long editing session, and I need to clean the code, I
can simply remove those local symbols declaration more easily, by remove the
symbols with the new color.
Right now, I have to check for each symbol, one by one, by doing Find, to
see if I am still using it or not.
In practice, I normally like to write small functions, so this is not a
problem, as I can easily see which symbol is used or not, but sometimes, I
have to write a large function, and I notice the need for this feature.
May be this feature can be added to version 8? (Unless one can do this now
in version 7, which I am not aware of).
