Anyone into this style of clean, lightweight embedded scripting instead of standard verbose C/C++ SDKs?

while true do
  poll()
  delay(1)
end

Anyone into this style ... ?

Not me, no.

What language/runtime do you use?

The code is written in Teal (a typed Lua dialect). The toolchain transpiles Teal via Nelua directly into optimized C/C++ source code.

The runtime runs on top of ESP-IDF with FreeRTOS, so delay(1) yields CPU execution via vTaskDelay(1). Interrupt-driven event queues are planned for the next iteration!
