Thus, what happens today? People ask Haskell-Cafe how to implement global variables and they are advised to use IORefs and unsafePerformIO, although the better answer is: "Why do you want to do this?" Even "Tackling the awkward squad" considers unsafePerformIO an acceptable tool for handling global configuration files.
One problem here is that the Haskell-style alternatives to global parameters
aren't as convenient as to use.
We should consider stealing Agda's module system for Haskell 2.0.
