It's not very consequential, but isn't totally pointless in my view:

"Terminator line is established for the data structure arrays which may have unknown,
to the caller, sizes. The purpose of it is to stop iteration over an array and avoid
out-of-boundary access. Nevertheless, we may apply a bit more stricter rule to avoid
potential, but unlike, event of adding the entry after terminator, already at compile time.
This will be achieved by not putting comma at the end of terminator line"



Anyway I can drop this change, it's just confusing everyone
