Uh, if you write the content of the included file _exactly_ where
\include #filename now is, you get _exactly_ the same error.  Your
inclusion works perfectly fine.  It's just that the syntax in the file
is not valid syntax inside of #{ ... #}.

If you want to include the file instead at the _top_ level, try

includeFunction = #(define-void-function (filename) (string?)
                     (ly:parser-include-string (format "\\include ~s" 
filename)))

However, depending on the context you use this in, you might get
surprised by just _when_ the inclusion happens.
