I see, yes, it cannot compare well to Python. So for when speed is
critical it is better using Perl. Perl is/was one of my favorite
languages and I did everything in Perl before learning about Lisp.
Lisp offers to me better simpler readability.
What I am missing is simple interface and that is solved with Emacs
built-in features. And Emacs than provides instability so I cannot
really solve huge tasks with it, it crashes, has memory problems,
etc.
