Oh, that pretty much sorts out my problem there, sorry if I 
glanced over it being mentioned previously.

And that also explains to me why having the values packed into a 
struct (e.g. C# FormattableString) wouldn't be acceptable either. 
Again, sorry if I missed it being mentioned before.

My main other argument was the possible complexity/bugginess of 
having functions that provide special support for these strings, 
as from Walter's DIP it seemed each function would have to 
implement their own parsing of the format string. But I see your 
DIP already addresses that (_d_interpolated_format_spec("")).

I'm kind of struggling to see now why your changes were so 
vehemently rejected now.

Other than that, just pretend my misinformed post doesn't exist.
