the recursive \include statement?I came across this when working with a include file collecting cue notes like that:
\include "foo1.ly" \include "foo2.ly" \include "foo3.ly" \addquote "bla1" { \foo1_bla1 } \addquote "bla2" { \foo2_bla2 } (...)I change my code to circumvent the recursive loop but I needed a moment to figure out why LilyPond was hanging.
A warning would be nice.Honestly I did not try it, but I am quite sure that it would be easy to implement a IFDEF mechanism like in C preprocessing with a few lines of Scheme, however.

It's just doing what you told it to do, and most other language parsers that have an "include" facility will similarly be unable to give a useful result when fed infinitely recursive include files. The usual advice to users is not to write such input.
