digitalmars.D.learn - std.net.curl not working in 2.058 for Windows

There is no documentation (both on dlang.org and in the local 
documentation) so I'm not sure if it's supposed to be working 
yet.  I get linker errors when I try to use it:

     [snip]

Furthermore the documentation in the actual source says this 
should work:

     string content = get("http://dlang.org");

But that results in a compiler error error:

     netcurl.d(5): Error: cannot implicitly convert expression 
(get("http://dlang.org",AutoProtocol())) of type char[] to string

get() signature from the source is:

     T[] get(Conn = AutoProtocol, T = char)(const(char)[] url, 
Conn conn = Conn())
         if ( isCurlConn!Conn && (is(T == char) || is(T == ubyte)) 
)

An .idup fixes it, of course, but the documentation is wrong (or 
the signature is wrong).

Finally, was the curl library included?  If not, where can it be 
found?  It needs to be an OMF version, right?  I don't see an OMF 
version on curl's website.

It would appear phobos's win32.mak wasn't updated to include the 
curl wrapper.

I can try to figure out how the makefile works and send a pull 
request if nobody who knows what's going on has time.
