In the mean time you can use a LUT to reduce the number of colors

Thanks - that's really useful. It also pointed me to a simpler way of
doing it:
If I have a 256c greyscale image with range 0-255, $image.pgm, then
this:
convert -fx 'r/8' -depth 8 image.pgm out.pgm
gives me the same image but with the levels squashed into 0-31.
However, If I do:
$image->Fx(expression=>'r/8');
In my perl, it makes no change to the image at all. Where am I going
wrong?
