I don't think we want to write them as function objects, because then
we'll again bump into the problem that some function objects contain
unprintable objects like buffers.

Better would be to print the "#<byte-code-function F85>" strings
as-is instead of printing them as #<string 540>.

Of course, we could also try to print the function objects and then
verify that they are printed readably and only print them as strings
when that fails.
