This used to work in older compiler (might have been v2.067 or v2.066, not older).

```
#!rdmd

import std.stdio;
import std.json;
import std.algorithm;

void main() {
	auto ls = File("../languages.json","r").byLineCopy().joiner.parseJSON();
}
```

Error: c:\D\dmd2\windows\bin\..\..\src\phobos\std\json.d(639): Error: variable std.json.parseJSON!(Result).parseJSON.json has scoped destruction, cannot build closure

Dammit, i am on windows, DMD32 D Compiler v2.068.0

Fixed it by changing into:

```
	import std.conv : text;
	string json = File("../languages.json","r").byLineCopy().joiner.text;
	auto ls = json.parseJSON();
```

Why would you read file by line and then merge all into one string? You end up with reading the whole file (well, getting rid of line ends) anyway, so probably the more efficient solution would be just read the whole file at once with std.file.read and cast to string.

Or just use std.file.readText:

Thanks for your advice. But that is not what I asked for.

The question was, why doesn't this work anymore with the latest (2.068.0 and 2.068.1) compiler:

```
auto ls = File("../languages.json","r").byLineCopy().joiner.parseJSON();
```

It should. Right?

I just ran into this as well. This seems like a regression.
