[NTG-context] Buffers vs. \def

Hello, a question - I'm just curious: What is advantage (or maybe intension) of using buffers over \def? Compare: ---- \def\BufA{This is buffer A.} \startbuffer[BufB] This is buffer B. \stopbuffer \starttext \BufA \getbuffer[BufB] \ifx\BufC\undefined No buffer C.\else\BufC\fi \stoptext ---- Both ways give the required effect. Moreover, when using \def, I can also test its existence (maybe it's also possible with buffers, but I don't know how). Best regards, Lukas -- Ing.
