You should probably avoid `-m32` in general (as dub does btw). for what it's worth... due to license restrictions and costs we are not allowed to have the MS toolchain installed on our office clients... tried it now @HOME with the '-m64' switch anabled, as suggested by you, and can confirm, it also "just works"...

Yes, use
[`get`](https://dlang.org/phobos/std_net_curl.html#.get):
```d
import std.net.curl;
void main()
{
char[] content =
get("https://gist.githubusercontent.com/deekayen/4148741/raw/98d35708fa344717d8eee15d11987de6c8e26d7d/1-1000.txt;);
}
```
On Windows:
```

Download a file into array (using std.net.curl.download)
Let's say I can't store information into files.
Is it possible to download a file into an array.
This is what I have now. It saves a download into a file named:
file.txt
import std;
import std.net.curl;
void main()
{
writeln("Hello D");
download("https://gist.githubusercontent.com/deekayen/4148741/raw/98d35708fa344717d8eee15d11987de6c8e26d7d/1-1000.txt;, "file.txt");
}
Also run.dlang.io seems to be blocking and not letting me to run
curl requests. I'm feeling sad right now.
