```The number snip doesn't add any new kinds of values to Scheme -- it's
just changing the way that existing numbers are printed. So, if you
wanted a new kind of number where the sqrt of 2 could be represented
precisely, the first step would be working out what all the numeric
primitives do on those new kinds of numbers and implementing that.

Once you've done that, you might be able to convince me to draw you a
little sqrt thingy. :)
