Calling the ``+``, ``++-++`` or ``++NOT++`` prefix operator twice does nothing: the second invocation undoes the first. Such mistakes are typically caused by accidentally double-tapping the key in question without noticing.
Either this is a bug, if the operator was actually meant to be called once, or misleading if done on purpose.
== Noncompliant Code Example
----
IF NOT ( NOT foo = 5 ) THEN -- Noncompliant
value := ++1; -- Noncompliant
END IF;
== Compliant Solution
IF foo = 5 THEN -- Compliant
value := +1; -- Compliant
