Max got stuck on the named parameters implementation. Moving 
forward with it is on is todo list. No one has submitted a new 
DIP for string interpolation yet.

This has been talked about for years, the DIP process is really 
slow or not moving forward at all, while users really want to use 
those *now*. So instead, I did it (string interpolation) in the 
lib:

This has nothing to do with the DIP process. No string 
interpolation DIP is in the queue right now.

I remember there used to be, maybe more than one string 
interpolation DIPs for years, so they all are got rejected?

Anyways，this is one of the most frequently asked feature in D. 
Even Python added into the language, not sure how many PEPs they 
have gone through. But I feel D is lagging far behind.

For this particular (relative simple) feature, I think we should 
Just-Do-It, that's why I named my package "JDI"util:

https://code.dlang.org/packages/jdiutil


Actually that's the spirit I want promote in the D community: 
there have been a number of known D issues unsolved for years, 
and people ask for their resolution again and again, so can we 
Just-Do-It?

You can see the status of any DIP that has undergone review here:

https://github.com/dlang/DIPs/blob/master/DIPs/README.md

Then at the bottom of each DIP, in the 'Reviews' section (linked 
in the TOC of each DIP) you can see a summary of each review 
round.

Walter rejected his own string interpolation DIP:

https://github.com/dlang/DIPs/blob/master/DIPs/rejected/DIP1027.md

A second one was withdrawn by the authors after two rounds of 
Community Review:

So thank you Mike and Max, your work and your success is very 
welcome!

Ok. My impression from the discussion was, that a new DIP was in 
preparation in the background - wishful thinking ? :-)

John Colvin and myself have had an idea on a DIP for string 
interpolation. We discussed it with Adam Ruppe and Steven Schveighoffer 
who found it satisfactory.

The work is at a stage where I need to edit the proposal (which is now 
in a private repo) to reflect that idea. With my changing jobs I didn't 
have the time to do so. Hopefully either myself or John could carry it 
forward in the near future.

Sounds good!
So the same for you and John: Thank you, your work and your

Wait, why is it in a private repo?

It's a draft not ready for review. Once it will be ready for review it 
will be of course published.

I thought it was public:

https://github.com/John-Colvin/YAIDIP

Or is that an old version?

If you need string interpolation yesterday and don't mind using 
mixins...

```d
import std.stdio;
import std.string;
import std.array;
import std.range.primitives;

string mwrite(string str)  safe pure {
	size_t istart;
	bool inword = false;
	auto result = appender!(string[]);
	auto vars = appender!(string[]);
	foreach (i, dchar c; str) {
		if (!inword) {
			if (c == '{') {
				result.put(str[istart .. i]);
				istart = i+1;
				inword = true;
			}
		} else {
			if (c == '}') {
				result.put("%s");
				vars.put(str[istart .. i]);
				istart = i+1;
				inword = false;
			}
		}
	}
	if (!inword && istart < str.length)
		put(result, str[istart .. $]);

	return format!`writef("%s", %s);`(result.data.join, 
vars.data.join(`, `));
}
string mwriteln(string str)  safe pure {
	string result = mwrite(str);
	enum toReplace = "writef(";
	return "writefln(" ~ result[toReplace.length .. $];
}

void main() {
	int x = 4;
	float y = 3.5;
	mixin(mwriteln(`X:{x} Y:{y}`));
	mixin(mwriteln(`Which is larger? {x>y?"X":"Y"}`));
}
```

Thanks, very cool result with little coding!
