How is it so? Recursion is the only possible form of iterative control flow in the functional languages. If you do not want to allow any forms of recursion, you cannot use functional languages at all.
Of course, you can explicitly demand totality, and it's perfectly fine, but still it is quite a severe limitation, and you'll have to allow optional unrestricted recursion if you want to have (at leat local) Turing completeness.
