It was excluded because the data is kinda redundant and I couldn't
come up with a sexy, convincing way how to denote this in the sources.

Adding this certainly makes, if you can come up with macro syntax that
makes this nice to read.

(I'd prefer if this would use \0 or so as separator though maybe,
given it sounds weird compiling in strings that the code first has to
parse, and if \0 is used as separator then things feel more
"pre-parsed" to me)

Anyway, by all means, please prep a patch set and submit as PR, and we
can continue discussions there!y
