I really wanted something like this when embedding serial numbers and keys in ROMs. At the time I was mostly working in C and PHP, so I was imagining something closer to a template language, but something like this would have given me a good intermediate step where I could have used PHP to render this text format and then ran that to produce the necessary bits on disk. A decade late for me, but still looks cool.
