Sometimes when one write a proc(), and later make changes, some of the earlier local variables could no longer used after the new edits.
In a small proc, it is easy to spot visually which ones are no longer needed and to remove them. But for a large proc() with many local variables, it is harder.
Does maple have a tool to help one find which are the unused local declarations are not used? For example
I'd like maple to tell me that `y` and `z` are unused when I asked it to. (may be by highlighting or warning)
Mathematica has such a tool (and more) in its workbench editor which is very useful. does one need an external tool in Maple to do this?
