  Heh, actually we probably have to talk about that.  The k should IIUIC be
swallowed by the %lf and the %c should fail; this is the production
described as NAN(n-char-sequence opt) in the C language spec, strtod
documentation (that's 7.20.1.3.3 in WG14/N843 draft, I don't have the final
version).  And we haven't even mentioned the lack of INF support yet :)

  However I'm on UK time, so it won't be happening today!


    cheers,
      DaveK
