If you insist that you know better and aren&#x27;t trolling, explain why Lisp isn&#x27;t used in the real world then?<p>CL is like the scripting languages in capacity and ease of development -- but more. And it is both faster and earlier than the 1990s, when those scripting languages started to grow like weeds. Why did Perl, Ruby, PHP et al eat CLs lunch?<p>(I&#x27;ve seen explanations that basically boil down to fashion, too many academics and&#x2F;or fear of different syntax. They seems possible, but hardly a reason why a capable tool was ignored? New things did get big around that time frame -- e.g. OO and testing -- so conservatism... hardly?)
