Copyless message passing is a communication paradigm in which only pointers are exchanged between sender and receiver processes. Because of its nature, this paradigm requires that messages are treated as linear resources. Yet, even linear type systems leave room for scenarios where apparently well-typed programs may leak memory. In this work we develop a polymorphic type system for leak-free copyless messaging in a functional setting, where first-class functions can be used as messages.
