+**************
+I also found a few bugs:
+
+* The examples in input/test/bar-scripts.ly and score-bar-scripts.ly
+ don't work. The problem seems to be that you can't define a
+ a score identifier and then use it in the \score block.

+************
+
+How can I specify a chord whose duration is longer than a whole note?
+
+ \type ChordNames { \chord{ A1*2-min } }
+
+gives me a parse error. And \times doesn't work either. I can't use
+a spacer note. So it seems to be impossible to have long chords of
+general length. Of course, in the example above I can use \breve.
+But what if I want a chord that lasts for 3 whole notes? Or what
+about 2.5 whole notes? Is there a mechanism for getting this kind of
+length?
+
+
+Why does my second extender request get junked in the following:
+
+\score{
+< \notes \relative c''{
+ a4()b()c()d c()d()b()a }
+ \type Lyrics \lyrics {
+ foo1 __ bar2. __ _4 }
+> }
+
+It seems that \cr and \decr don't work any more.
+
+\score{
+ \notes{
+ a \cr b \rc c }
+ \paper{linewidth=-1.;}
+}
+
+Gives me
+
+qq.ly:3:9: warning: can't find (de)crescendo to end:
+ a \cr
+ b \rc c }
+
+
+
+Use of semicolons is still rather confusing. They are obligatory
+after some types of assignments and illegal after others.
+
+ \property foo=bar illegal
+ foo = 3 at top level illegal
+ foo = 3 inside \paper obligatory
+ foo = \notes{ ...} top level illegal
+ foo = \translator{ } in \paper obligatory
+
+As far as I can tell, the sole accomplishment of this syntactic
+irregularity is to keep the user as confused as possible.
+
+
+I was trying to get interstaff beams to work and did this:
+
+\score{
+\type GrandStaff <
+\type Staff=one \notes\relative c'{
+ \stemup
+ [c8 c \translator Staff=two \stemup c c]
+ \translator Staff=one
+ \stemdown
+ [ b8 \translator Staff=two a8]
+ \translator Staff=one
+ c4
+ }
+\type Staff=two \notes{ \clef bass; s1 }
+>
+\paper{
+ \translator{
+ \GrandStaffContext
+ minVerticalAlign = 3.0*\staffheight;
+ maxVerticalAlign = 3.0*\staffheight;
+ }
+ linewidth = -1.;
+}
+}
+
+The beams are at the right angle, but they aren't in the right place.

+
+I use the following, which should definitely be provided somewhere
+in guile, but isn't, AFAIK:
+
+(define (hash-table-for-each fn ht)
+ (do ((i 0 (+ 1 i)))
+ ((= i (vector-length ht)))
+ (do ((alist (vector-ref ht i) (cdr alist)))
+ ((null? alist) #t)
+ (fn (car (car alist)) (cdr (car alist))))))
+
+(define (hash-table-map fn ht)
+ (do ((i 0 (+ 1 i))
+ (ret-ls '()))
+ ((= i (vector-length ht)) (reverse ret-ls))
+ (do ((alist (vector-ref ht i) (cdr alist)))
+ ((null? alist) #t)
+ (set! ret-ls (cons (fn (car (car alist)) (cdr (car alist))) ret-ls)))))
+
+If you want a C version, you can run the above code through hobbit, or
+tranlate it to C by hand.
