I agree with you 100% plus, I'd like to take it up a notch by saying that Pure FP evangelists are the sole reason why Scala is not widely used.

Also, it is not seldom that you hear them say "It took me n years to fully grok the _whatever FP concept_". Or Martin Odersky doesn't get the _whatever FP concept_.

So how do they expect the majority of sw engineers will use/adopt those principles if the guy who invented Scala "does not get it" and even themselves took so much time to "get it"...???
