True, it's not that the stacks and whatever don't matter at all, just that they'll change, you will have to learn new ones, and so any kind of religious attachment to one is a sign of an amateur programmer (in the Gerald Weinberg sense).

I, too, really like functional programming for that very reason. :-) It just isn't the approach I grew up with, and the functional programming manner of dealing with imperative is still a bit hard to get my head around.
