Apologies for the lack of clarity. Yes, I find I really like using Julia from start to finish and really admire that I can do so without compromise.

I find this approach to be straight up superior to the usual pattern where one starts out in a slow dynamic language to build the prototype and then either replaces certain functions with interop calls to a fast language (losing all the features that brought you to your dynamic language in the first place!) or straight up replacing your entire prototype with a production version written in your fast language and providing bindings to your slow language.
