But tags DO have a result: namely, an XML output.
So for the processing of XML objects, jelly IS functional.
Trouble of course start if you want your tags to return anything else than XML. And this is the place where I suggested an extension for being functional is to be inserted.
There's one seducing feature seen in some functional languages that I feel you forgot: lazy evaluation: e.g. that an expression is to be evaluated only when it's needed. This is missing just about everywhere but I have the impression that making something such in Jelly would be do-able.

happy to renew those discussions again.
