 I'd be glad to!

 I can live with this but why do we need to make the delimiter sequence so
long? If you like Java text blocks, which use the same delimiters as Python
raw strings, why not do the same thing and write

---------------------------------- >8 --------------------------------------
std::string const simple_table_header =
1 + R"""(
Table number: 1
Table type: Aggregate
Minimum age: 0
Maximum age: 1
Number of decimal places: 5
Table values:
)""";
---------------------------------- >8 --------------------------------------

? This seems quite readable to me and it's short and memorable enough to
use it without having to look it up every time.
