how to check for unnecessary local declarations?

[Tiemo Hollmann TB]

Hello,

I am using the strict compilation mode. When working over longer time on a
project it regularly happens that I have orphaned local variable
declarations.

Actually they don't hurt, but I like to keep my code clean and wonder if
there is any hidden feature, which checks for not any more needed local
declarations (beside scripting a check myself)?

Thanks

Tiemo
