Hmm.  Maybe.
It would be useful for other kinds of spanners, and also articulations
(for example to place a turn during a note).  Would creating macros
for all of them be feasible? (maybe i miss something obvious?)
My rough idea would look something like this (this is just a musing,
not a proposal for discussion yet):

{ b2 \<@0.5 a2 address@hidden } meaning { << b1 { s2 \< s2 \! } >> }

Attached.

Not quite :)  \arpeggioUpWithHairpinDown and
\arpeggioUpWithPianoFirstThenHairpinToPianissimo don't sound like fun!
;)

That's more like it, but i'm not totally sure.
What i think of is a general way of attaching objects to another
objects.  For example '&' would attach objects:
<c e g>\arpeggio&\<  meaning  a hairpin attached to arpeggio
g\fermata&\markup \italic {10 seconds}  meaning  a "10 seconds" markup
attached to the fermata.

Again, this is just a musing for now.  I'm still looking for objects
that attach to other objects; i'll post something about it on new
GLISS mailing list, ok?

cheers,
Janek
