I think the complexity for the syntax and the language itself is
quite little - and it's basically the same thing as JS template
string literals too, but with the special ignore cases for
letters i/r/q. It's not going to solve any issues if nobody
implements it. It's completely just an extension to the language,
but then is going to be a big help to making both more pretty
code with `text`
The implementation of these functions is going to be a little

I can see that the new istring calling syntax could introduce
issues if we want to add more string types through prefixes in
the future, but I think that would be worth it for a quite
versatile feature. The feature in other languages (like JS) has
shown great use-cases, an example:
^ that link contains lots of cool examples we could have in D
like that too. Some type-safe data structure creation helper,
some string / template language processors with nicer syntax,
some useful every-day utilities.
I think overall it will solve more issues than introducing new

it's a complex feature. However you don't really care about its
implementation or complexity unless you want to implement a
function for it yourself. All the average user might even want to
think about is `text"..."`, which you could look at like it's
special language syntax. It's something library authors can use
and document to make more readable, better library functions.
Overall I think there is more benefit in adding this than not
