digitalmars.D - run.dlang.io dmd version < 2.086 fail

The "All dmd compiler versions" is an incredibly useful part of the 
online editor/playground, but versions prior to 2.086.1 seem not to be 
installed correctly:

```
onlineapp.d(1): Error: module `std` is in file 'std.d' which cannot be read
import path[0] = /path/to/dmd.linux/dmd2/linux/bin64/../../src/phobos
import path[1] = 
/path/to/dmd.linux/dmd2/linux/bin64/../../src/druntime/import
```

whereas subsequent versions run (and succeed/fail as expected depending 
on code and features used)

What code are you trying to run? `std` is a fresh addition. it 
wasn't available in the older versions.

The default "Hello D" provided by the playground. A quick swap for 
std.stdio fixes -- thanks for pointing this out.

Replace "import std" with "import std.experimental.all".

 Replace "import std" with "import std.experimental.all".


`std.experimental.all` was introduced in the DMD 2.079.0 release 
[1], however starting with DMD 2.086.0 it was deprecated in favor 
of simpler `std` package name [2]. Usually, the D deprecation 
process is around 2 years (or 12 major releases), but since this 
feature was experimental (hence the std.experimental.all name), 
the deprecation process was fast tracked. `std.experimental.all` 
will most likely be removed starting with the 2.090.0 release.
