Using the same value on either side of a binary operator is almost always a mistake. In the case of logical operators, it is either a copy/paste
error and therefore a bug, or it is simply wasted code, and should be simplified. In the case of most binary mathematical operators, having the same
value on both sides of an operator yields predictable results, and should be simplified.
This rule ignores *, +, &, <<, and >>.
Noncompliant code example
If (a = a) Then
doZ()
End If
If a = b OrElse a = b Then
doW()
End If
Dim j = 5 / 5
j = 5 \ 5
j = 5 Mod 5
Dim k = 5 - 5
Dim i = 42
i /= i
i -= i
