I'm still planning to work on this for most of the "basic" Sage types,
but I don't know when I'll get to it; if anybody wants to help, let me
know! (The basic framework is in place in sage/misc/sage_input.py,
and there's quite a bit of documentation on how to write the per-type
code at the top of that file.)
