Change the default type from any to $any for ISL 2.0.
Default type:
A type consists of a collection of zero or more constraints. The set of values which belong to a type is the intersection of the values that satisfy each constraint. In order for a value to be a valid instance of a type, the value must not violate any of the type’s constraints. A type definition with no constraints is equivalent to $any.
