Thanks, but the comment you linked to is just a list of disagreements without explanations (whose author even admits it later by stating that &quot;simple ridicule is both easier to write and more entertaining to read&quot; (!)).<p>I was hoping for something more tangible. Searching wikipedia doesn&#x27;t support the author&#x27;s claims about FP ( things like &quot;FP is about higher-order abstraction facilities, not immutability&quot;).
