+\citet{FowlerLMD19} uses effect handlers in the setting of linearly
+typed fault-tolerant distributed programming. They use effect handlers
+to codify an exception handling mechanism, which automatically
+consumes linear resources. Exceptions are implemented as operations,
+that are handled by \emph{cancelling} their resumptions. Cancellation
+is a runtime primitive that gathers and closes active resources in the
+computation represented by some resumption.
