I highly support this, as I've currently got a program that's both
slightly broken (because I don't hack around the issue for lengths)
and annoyingly complicated (because I do hack around the issue for
colors).  The color issue is especially annoying, since I'm having to
reimplement a full <color> parser in my PHP.  IIRC, every single
rendering engine returns something different when I do
$(elem).css("color") for an element with "color:blue" set in CSS.
