Oh, sure, but once you start playing &quot;there&#x27;s nothing new under the sun&quot;, the mainframe guys will eventually come along and explain how they were doing all that in some vastly more sophisticated way back in 1962 using systems none of us have ever heard of. So what? I don&#x27;t care. I just think that the definition of &quot;practical&quot; is shifting, and I want to play with another way of doing things in case it turns out to suit my needs better.
