This really resonated with the way I feel about Ruby. I haven't had the opportunity to seriously write Ruby in years, but I measure every development environment against the classic ruby/rails/rake/gem/bundler experience and I always find myself missing how productive Ruby was to work with, inside and outside of Rails. I think Ruby particularly excels in its ability to mold itself structurally to match its problem domain. Rspec and ActiveRecord and to a lesser extent Bundler and Rake are still the most ergonomic versions of tools in their class that I have used to date, and they all expose some sort of powerful DSL that feels magical in just the right way.
These days I mostly use more "serious" languages (python, Java, C#, C++), but it's because I want to work on a domain within those languages and I don't have the time to commit to bringing the domain to Ruby. I should call her...
