I am using ghc-6.4.2 from darwinports on OS X 10.4.7
Can I help confirm / test this with something test cases?
Sorry, I don't really understand what you mean. You already told us the following:
I cut and pasted your code [i.e., the example code of my first e-mail concerning this topic] into ghci-6.4.2 with -fglasgow-exts and there was no error. And I can (print (showSnd (Pair A True)) and (print (showSnd (Pair B 8))) but when I try to compile it with ghc-6.4.2 it complains about the Show instance. I find this deeply wierd, and it seems like a bug.
Simon, don't you experience the same problems on your machine? Should this be a Mac-only problem? Best wishes, Wolfgang
