Hi,
I'm looking for a function that converts my hex-string to a binary
representation. In Python I write the following:

myHex = "123456789ABCDEF"
myBin = myHex.decode('hex')

But how to do the same in D? Is there any function?

Thanks for suggestions!

    import std.stdio;
    void main(){
        import std.conv;
        import std.format;

        auto i = to!ulong("123456789ABCDEF", 16);

        writeln(format("%b", i));
    }

Thanks to all of you for the solutions, but what if the hex-string
exceeds the limit of ulong, for instance
"123456789ABCDEF0123456789ABCDEF1234". How to convert them to a
ulong-array?

Well, technically, a hex string can be split on 16-character boundaries, 
and then you could parse each one.
