Just under a year ago I started building a BEAM language with dependent types and first-class FSMs—chose the wrong implementation language, wrote spaghetti, had an LLM tell me it was garbage, shipped something embarrassing, then spent months rethinking. Here is what I learned and where Cure stands today.

BeamBloggers is a specialized resource center for Apache Beam enthusiasts, offering an extensive array of tutorials, use cases, and best practices for mastering the Apache Beam framework. Developers can explore  guides on building robust data pipelines, processing large-scale datasets efficiently, and deploying real-time analytics solutions using Apache Beam and its ecosystem of tools.

A developer shares a year-long journey building Cure, a new programming language targeting the BEAM VM with dependent types and first-class finite state machines. After an initial failed attempt using Erlang that devolved into spaghetti code, the author regrouped, switched to Elixir, built a proper MetaAST foundation via the 'metastatic' library, and restarted with a disciplined, incremental approach. Key lessons include choosing the right implementation language, keeping the AST central to the architecture, and avoiding feature creep.
