Half a decade is nothing to most programming cultures.

Nobody is forcing you to be part of that. There are a lot of places ... Perhaps I'd rather help those who need it than preach to the converted. You summed it up nicely as two problems: (1) bitchy managers and (2) untrained programmers. I'd like to use Haskell to help with (2) but I still have to work around (1). My plan is to start by winning the hearts and minds of the developers before sticking my neck out far enough to get it severed. There's another plan where I'm pitching VCs about a start up, in which case I'd have a lot more control, but I'd still have to prove that my elite imperative squad were willing and able to learn a new trick before committing myself. I've actually learned quite a lot from this discussion and that largely enables me to preempt any Rails-day problems. But that's only me. Lots of people might be flirting with Haskell just out of curiosity and bouncing off it for these reasons. There have been a lot of good ideas suggested about how to minimise that, and I'd also throw in that it would be cool if people could tell the compiler to behave as it did half a decade ago when the code was written so people could prove to themselves that the code works in principle, then they could clock the compiler forward little by little, reading its release notes along the way. That's a lot friendlier than being confronted with an apparently endless series of error messages when you've barely learned to read them, and not even knowing if you're making things better or worse. If the desired compiler/modules version was in the makefile, that, I think, would be a general solution. The FPComplete thing also looks helpful. I could use that to sell the language to newbies. The mercenaries would come later though. Thanks to everybody for helping out with this. Adrian.
