No apologies needed, on the contrary, thank you for looking at it.

The "unprintable entity" comes from desktop--v2s, looks like it doesn't
handle compiled function values, so that's why :print-func and
:insert-func get messed up like that.

I guess if you save a position in a buffer, then kill the buffer.
