Variables declared with ``++var++`` have the special property that regardless of where they're declared in a function they "float" to the top of the function and are available for use even before they're declared. That makes scoping confusing, especially for new coders. To keep confusion to a minimum, ``++var++`` declarations should happen before they are used for the first time. include::../noncompliant.adoc[] include::../compliant.adoc[]
