State of formatted input

[Ali Çehreli]

(This question hasn't received an answer at d.D.learn.)

What is the state of formatted input? There has been changes at some 
point and at least %x and %o don't work anymore:

     int i;
     int j;
     readf(" %o %x", &i, &j);

phobos/std/format.d(2690): Parsing spec 'o' not implemented.

Same for %x. Of course %s works but doesn't know octal or hexadecimal. 
Is this ever going to be implemented, or is there a different method?

Thank you,
Ali
