We'd need to define what "sameness" means. If this goes toward "exact
match in binary representation", this gets a thumbs-up from me.
As a first step in that direction, I'd see adjusting send() and recv()
functions to use a portable binary format. A "sameness" operator could
then be implemented by simply comparing two value's send() outputs.
