Introduced in version: 1.3 (29 Jan 2020)
Using the same value on either side of a binary operator is almost always a mistake.
In the case of logical operators (and/or), 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 (-/:/div/mod), having the same value on both sides of an operator yields predictable results, and should be simplified. Plus and multiply operators are excluded from this check.
Noncompliant example:
if $Variable1 != empty and $Variable1 != empty
Compliant example:
if $Variable1 != empty and $Variable2 != empty
