Which has to be an exaggeration, though "for most objects" might
be true.

If repr is really used as a marshalling function, then the people
who are using it ought to be asking for something that can work
more reliably, a dedicated function that doesn't have to produce
something also intended for human eyes.  This function can fall
back on __repr__ the way str does.

If it really isn't seriously needed as a marshalling function, then
that notion ought to be forgotten, and some of the attendant issues
can be resolved (seems to me there was an issue with floating point
precision, for example.)
