If you don't know what Java is, you are not in the Clojure target market.

Then they should stop talking about it in /r/Lisp. Nobody there wants anything to do with Java, but Clojurians won't shut up about it.

There is a subtle difference between knowing what river is and knowing how to get to the other bank.

One could say the same for a plethora of programming languages some research is needed and we don't have to resort to extreme cases.

Out of the top of my head:

- There is the Python 2.7/3.X situation still going on, then there are the several distributions of python.

- GNU's R has a similar problem

- Installing gcc on windows was (perhaps still is) a confusing mess for a newcomer.

IMO I did not find installing clojure any harder than installing Scala for instance, and yet I have never heard (anecdotal, I know) complaining about Scala.

The user above mentioned that for _them_ the installation experience of a programming language matters a lot, and that they found the installation experience of Janet superior to Clojure.

You might not share that users preference of caring about the installation experience of a PL, but arguing that this user's preference is somehow unfair because many other languages also have bad installation experiences makes absolutely no sense.

the comparison was to Janet, not Python, R, C or Scala

Isn't GCC on Windows just unzipping a zip file and adding that location to path?
