If I understand correctly, the "returned value" is really calling this:
function display(d::REPLDisplay, ::MIME"text/plain", x)
> io = outstream(d.repl)
> Base.have_color && write(io, answer_color(d.repl))
> writemime(io, MIME("text/plain"), x)
> println(io)
> end
> display(d::REPLDisplay, x) = display(d, MIME("text/plain"), x)
So there is a quick way to short-circuit the displayed value (without
changing Base for everyone else):
julia> x = one(UInt8)
> 0x01
> julia> Base.display(d::Base.REPL.REPLDisplay, x::Unsigned) = println(x)
> display (generic function with 11 methods)
> julia> x
> 1
The nicest solution (IMO) is letting a user turn on/off this functionality
dynamically for whatever types they want, and setting display format easily
for a session. I think all this belongs in Formatting, not in Base.
