• Carl Sturtivant (9/9) Jan 17 Hello,
• Paul Backus (16/25) Jan 17 There's a function that does this in Phobos, but it's `private`.
• Carl Sturtivant (2/16) Jan 17 Great! I'll use that!

Hello,
I'd like a function like this,
```
string image(string s)
```
that maps any string s into the doubly quoted backslash escaped 
text that would be a string literal for s were it pasted into a 
program. Perhaps with a second parameter with detailed options.

Is there something out there I could use?

There's a function that does this in Phobos, but it's `private`. 
Currently, the only way to access it is by calling `to!string` or 
`format` on a range that contains the string you want to convert 
as an element:

```d
void main()
{
     import std.range, std.conv, std.stdio;

     string s = `"foo"\bar`;
     string escaped = only(s).to!string[1 .. $-1]; // slice off [ 
and ]
     writeln(escaped); // "\"foo\"\\bar"
}
```
