A true coder wanting to implement things near correct with algorithm complexity (big O), will try to find how to implement the right code by taking time to research understood and time tested patterns they&#x27;ve learned (it is an applied science after all) and implement them.<p>Saying the average joe doesn&#x27;t care to understand what his&#x2F;her Lang is doing under the hood which will doom them to repeat complexity that many here will respond with &quot;duh&quot; is not justification that a Lang is better - because it supports that behavior &quot;better&quot;.<p>I don&#x27;t know erlang that well but I&#x27;ll be damned if I don&#x27;t spend the time to find out how to properly do M:N with efficient tail recursion.<p>If one doesn&#x27;t care for efficiency at all then who cares about benchmarks?
