Thanks, that's very valuable information. It's hard to appreciate the relative utility (as you can see :-)) of different experimental features.
It's also confusing that things like exceptions, concurrency, and FFI are labeled 'experimental'. They're so (IMHO) crucial that I find myself saying, "Okay, if exceptions are 'experimental', what other really important things might I be missing by not being familiar with all the experimental extensions?" Thanks for clearing that up somewhat.
I have been writing substantial Haskell programs and I use *NO* experimental features. What I'm currently working on is over 20000 lines of Haskell 98. No extensions whatsoever. (It even compiles and runs with all available Haskell implementations.) Granted, I write mostly compiler like programs (files in, files out), but there is still a lot you can do in Haskell just as it is. Sometimes it might require bending slightly backwards to get it done, though. -- Lennart PS. OK, a small confession, that program contains one unsafePerformIO for performance reasons. It works fine without it, but 5% slower.
