Variable Not Assigned

Warns about variables that are never assigned.

Reasoning

A variable that is never assigned is probably a sign of a bug. This inspection may yield false positives if the variable is assigned through a ByRef parameter assignment, or if UserForm controls fail to resolve, references to these controls in code-behind can be flagged as unassigned and undeclared variables.
