What's the status of Cakelisp?
I use it every day. It is great for me. I've programmed my watch, my phone, my handmade mechanical keyboard, my current paid contract gig project, and more using Cakelisp.
I wouldn't recommend others use it because they can likely get similar success from creating their own C compile-time code generation/metaprogramming and custom build systems, similar to what Ryan Fleury did with RADDebugger. Taking ownership of your toolset and customizing it to your use case is the lesson to be learned here, not using someone else's exact tools. Different problems require different solutions.
I'm extremely glad I invested in building Cakelisp and continue to reap benefits from it.
