In 2.16.0 creating a book inside #{ #} returned the book. In 2.16.1 and
2.16.2 this is no longer always the case. Here's an example which fails:
============
\version "2.16.2"
makeBook =
#(define-void-function (parser location) ()
(let ((the-book
#{
\book
{
\include "header.ily"
\score
{
\new Staff
{
c'1
}
}
}
#}))
(display the-book) ;;; in 2.16.2 #<undefined>
(newline)
(print-book-with-defaults parser the-book)))
\makeBook
============
header.ily just contains:
============
\header
{
}
============
If you take the \include out or put the header inline it compiles, but that
defeats the purpose.
I just tried 2.17.10 and the behavior is fixed there.
