Have you thought about supporting format specifiers as well?
I looked at the C#
version and it looks like they can specify them using a colon
like this:
$"{a} in hex is {a:x}"
There are additional problems, such as:
$"{a} in %s {b}"
and positional parameters:
$"{a} in {0}"
Of course, the easiest solution is to just disallow that stuff.
What about supporting an optional prefix inside the {} like:
int year = 2017;
format($"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.
