Summary: We define a type and effect system for a \(\lambda \)-calculus extended with side effects, in the form of primitives for creating and accessing resources. The analysis correctly over-approximates the sequences of resource accesses performed by a program at run-time. To accurately analyse the binding between the creation of a resource and its accesses, our system exploits a new class of types. Our \(\nu \)-types have the form \(\nu N . \tau \vartriangleright H\), where the names in \(N\) are bound both in the type \(\tau \) and in the effect \(H\), that represents the sequences of resource accesses.
