I assume you mean \typeout instead of \typeput, then this is what
I get now:

  DEBUG: macro:->\protect \ref
  {section:deb-term-maintainer}macro:->3\hbox {}mac
  ro:->3.1\hbox {}macro:->3.1.0\hbox {}macro:->3.1.0.0\hbox {}

So I guess the \protect prevents the expansion? Is there a way I can
"unprotect" it in the \ifx statements?

Right.

I tried that before and it makes no difference: with hyperref
loaded, it'll be \ref{...}, if I do not load hyperref, then it is
expanded and the whole thing works.

  \def\refother{#1~#2}%
  \show\curref
  \show\thesubsection
  \typeout {DEBUG: \meaning\curref \meaning\curchapter \meaning\cursecti...

yields a compilation error:

  ! Argument of \show has an extra }.

                \par

Yes:

  ! Use of \@rule doesn't match its definition.
  \@ifnextchar ... \reserved at d =#1\def \reserved at a {
                                                  #2}\def \reserved at b {#3}\f...

Ah, I shall try that. However, what is a bit sad is:

  Note that the references create by smartref and byname are *not*
  hyperlink, when hyperref is active. Maybe in the future ...

Thanks for your input. Maybe I can get my simple approach working
somehow, and I'd appreciate any hints.
