Author here. I have written this language for many reasons but I won't detail here, I'll just say it's a lot of fun for me to design a language and write a compiler.
This language is a playground where I constantly add and remove features or try various experiments, so I have no intention to promote it. The only reason I have published it is that I publish an open source text editor written with this language.
After twenty years of evolution, it starts to become stable but not yet, I had recently added some basic option types.
