Barring people who are new to FP and reading through a tutorial, who can make erroneous claims out of lack of understanding (just like people learning OOP also make mistaken claims about it), I don't see how anyone using FP can make that claim. It's evident that you cannot arbitrarily change the order in a series of transformations unless they are commutative. I mean, this is already the case with maths! Who would claim it isn't with FP?
Yes, thank you, I wrote this comment and then saw your other comment. Below that comment I explained why I think your interpretation of what those people are claiming is mistaken. Mind you, not a case of No True Scotsman: I'm saying they aren't arguing what you say they are arguing; at worst they are being unclear, but they are certainly arguing something very different!
