If this list rounds up the most-used Haskell programs, I can safely conclude that I don't use any Haskell program besides Pandoc.

Apparently I use a few Go programs--Docker, maybe others?--but no Java programs at all, because I delete all the JVMs from my machines without noticeable effect. Likewise, no C# programs, because I have no Mono runtime. Probably no Lisp, Smalltalk, Julia, or OCaml. Some things I run almost certainly are or use Lua, and of course Python, Perl, and even Tcl. I don't know of any in Rust, but it would be hard to tell because of static linking.
