How to use unsafePerformIO safely?

[…] Or do you know of an existing blog post / other resource that addresses this?

• A Partial Rehabilitation of Side-Effecting I/O: Non-Determinism in Non-Strict Functional Languages(PS) - Manfred Schmidt-Schauß

  […] It is interesting that novices in lazy functional programming in general expect that there is some direct (side-effecting) I/O using a function call. […]

  • FUNDIO: A Lambda-Calculus With letrec, case, Constructors, and an IO-Interface: Approaching a Theory of unsafePerformIO - Manfred Schmidt-Schauß

    […] The common method to relieve the programming language designer from the inherent IO-problems is to shift responsibility to the programmer who has to sequentialize all IO-requests. This is also true for the monadic approach implemented in Haskell. […]

    […] It is possible that a declarative programming style for the IO part of a program can be integrated into Haskell.
