When I use the phrase "too slow" I am referring to being slow _relative to other interpreters_ I use, such as the Almquist shell intepreter (NetBSD sh or Debian's dash), the ngn-k interpreter, the spitbol interpreter, the dino interpreter, the lua interpeter, etc.

HN commenters often state that "Python is (pre)installed everywhere"

This is not true on the computers I operate. For example, there is no python interpreter in NetBSD's base.tgz

Here we see a project that uses Python to run the shell, even though, if HN commenters are correct, "Python is (pre)installed everywhere"

Of course, the shell _is_ preinstalled everywhere and this project relies on that fact

IME, the shell and other interpreters are much faster than Python for what I need to do

I am aware of Python's current speed as it is sometimes a compile-time requirement for third party software that I am compiling. I remove Python after I am done
