Internals questions - \include and LilyPond assignments

[Ian Hulin]

Hi all,

A couple of questions in case someone with more internal code-fu than me
can save me rummaging around in the guts of the C++ code, just so I can
get a handle on some behaviour I've noted trying to get LilyPond to fire
up with Guile V2.0.3.

1.  Does processing a file via \include cause a new LilyPond scope ->
    generating a new "anonymous" Guile module for that file?
2.  How and when does a LilyPond assignment
    blah = { lily-statements... }
    get compiled down in to a scheme (define blah .... )?
    Guile V2 complains about stuff like
    ignatzekExceptionMusic = { blah blah2 blah3}
    .
    .
    .
    ignatzekExceptions =
      #(sequential-music-to-chord-exceptions ignatzekExceptionMusic #t)
(end of guile traceback says)
.
.
.
