This reminds me of the idea behind Lua - similarly the original users needed a configuration format which became increasingly sophisticated and at some point the authors realized they needed “proper” programminglanguage constructs.
This is also why Lua is called Lua, the original configuration language was called SOL, for Simple Object Language. It never shipped, by the time the desired code was delivered to Petrobras, it was the first edition of Lua.
The authors have a fun read[0] about the history of the language, for the curious.
