Detailed Description

A position describes a value on the input IR on which a predicate may be applied, such as an operation or attribute.

This enables re-use between predicates, and assists generating bytecode and memory management.

Operation positions form the base of other positions, which are formed relative to a parent operation. Operations are anchored at Operand nodes, except for the root operation which is parentless.
