I wasn&#x27;t actually looking to argue; I was looking to understand.<p>And I guess it&#x27;s going to come down to &quot;whose definition of FP are we using?&quot;  If FP means &quot;I can write in a functional style&quot;, there are many more functional languages than if FP means &quot;I can <i>only</i> write in a functional style&quot;.  That debate - about whose definition of FP is correct - is one that I can&#x27;t bother to care very much about.
