What about supporting an optional prefix inside the {} like:
int year = 2017;
format($"The date is {%04d year}");
so if there is a % immediately following the { then the chars
until next whitespace is format specifier. You can of course
leave out the format specifier and it will default to %s.
I really don't see how string interpolation is better then
` "The date is " ~ format("%04d", year)); `
As mentioned before it is only because it is such a common
pattern that it justifies the change. Seems like many other
languages reached that conclusion as well.
Also take a look at a more realistic example with some more
formatting and it will be more obvious (at least to me it is :) )
"The date is " ~ format("%04d", year)) ~ " and " ~ user ~ " just
logged into " ~ here;
$"The date is {%04d year} and {user} just logged into {here}"
