Why not? then who would want multi-line prints would do the 'oppoite' of the
above,
right?
scheme@(guile-user)> ,use (ice-9 pretty-print)
scheme@(guile-user)> ,o print (lambda (repl obj) (write obj) (newline))
Or, as I do in Guile-CV, implement a specific display method for 'their
objects' (im-display in guile-cv, and the manual says 'to be used with
caution...)

What surprise(s)? :),
I mean, what sort of code or who's the one of us who would rely on the repl
print
'layout' in any sort of way(s)?

It seems to me it is a yes :)
note that (just not to forgot), we need this to be done both for the
repl
_and_ exception printers as well ... it is as essential if not more then
within the repl

I'm actually using truncated-print all the time, since it is simply impossible
otherwise to use/develop guile-v, and I never spotted any 'problem' (not to say
I
can guarantee there is none of course, but that did not happen in years). Then
we
could always improve when someone report a problem ...
Thanks,
David
