An extension of the λ-calculus is proposed, to study resource usage analysis and verification. It features usage policies with a possibly nested, local scope, and dynamic creation of resources. We define a type and effect system that, given a program, extracts a history expression, that is, a sound overapproximation to the set of histories obtainable at runtime. After a suitable transfor- mation, history expressions are model-checked for validity. A program is resource-safe if its history expression is verified valid: If such, no runtime monitor is needed to safely drive its executions.
