FX-87 - Effects. A polymorphic language based on Scheme, allowing side
effects and first-class functions. Attempts to integrate functional and
imperative programming. Expressions have types, side effects (e.g.
reading, writing or allocating) and regions (stating where the effects may
occur). "The FX-87 Reference Manual", D.K. Gifford
et al, MIT/LCS/TR-407, Oct 1987. Version: FX-89.
