[NTG-context] Test for existence of a Ctx buffer by Lua

Hello, how to test by Lua whether a Ctx buffer exists? --- \startbuffer[A] Aaa aaa \stopbuffer \starttext \getbuffer[A] Test %\getbuffer[NonExisting] Vvv \stoptext --- To get something like 'context.buffers.A' -> no-nil and 'context.buffers.NonExisting' -> nil? Best regards, Lukas
