Can Vibe.d use a proxy to download files?

[GoogleIsEvil]

If not could it be added. I'd like to download files through a proxy.

Best I could find is a settings.proxyURL to specify the url but this does't seem to exist any more:

I've tried stuff like:

void dl()(string url, string filename)
{
HTTPClient client = new HTTPClient();
HTTPClientSettings settings = new HTTPClientSettings;
settings.proxyURL = URL.parse("http://127.0.0.1:18080");

download(url, (scope input){
	auto fil = openFile(filename, FileMode.createTrunc);
	scope(exit) fil.close();
	fil.write(input);
}, settings);

//download(url, filename);

}

but to no avail.
