There's an implementation here:

http://www.home.f4.ca/sean/d/

It could probably be improved as it uses dchars internally, but it's a 
complete and correct implementation of scanf from the C99 spec plus some 
additional support for D types.  Throwing exceptions out of the function 
could be accomplished easily by rethrowing from the appropriate catch 
block at the bottom of unFormat.  Please note that this currently 
requires the updated utf module it contains, though I believe it could 
be rewritten to grab a single char and use stride() to determine how 
many more were expected--I wasn't aware of stride() when I wrote this 
code a year or so ago.  If there were real interest in getting this into 
Phobos I could probably find the time to make any requested updates 
myself, but I'm too busy to do so for any other reason.
