Ruby 3.0
I wrote a coule of small CLI tools in Ruby. I really liked how a single line could do a lot of work and those fancy syntax sugars. But I found it difficult to work with due to bad code completion suggestions in IDEs and overall poor documentation.<p>I never knew what objects a function could return without reading the code or trying to call it first and inspecting the response.<p>Then I switched to Go and Python and found those best-suited for all my needs.
