+Arpeggios may now use ``parenthesis'' style brackets:
+
+@lilypond[relative,ragged-right]
+ \override Arpeggio #'stencil = #ly:arpeggio::brew-chord-slur
+
+ % Note: does not work for cross staff arpeggios.
+ \override Arpeggio #'X-extent = #ly:grob::stencil-width
+ <c g' c>2\arpeggio ~ c
+@end lilypond
