Check out readf: http://d-programming-language.org/phobos/ std_stream.html#readf

You'll need to wrap the string in a Stream interface (MemoryStream?), but since you're looking for advance-on-read, you want stream semantics anyhow.

I've never noticed std.conv.parse takes a radix argument, silly me.
And will take
a look at readf from std.stream, definitely.

Thanks!
