Re: Regarding "unhelpful error messages.." (reproduction)

[Graham Percival]

Hi Simon,

Please include complete examples in bugs.  Your include line
\include " svenska.ly <http://svenska.ly>"
and use of notes like
dess8
make it impossible for me to test this.

That said, there was a bug that was recently fixed that disallowed music 
functions with more than three variables.  I suspect that your example 
will work in 2.9.19.

Cheers,
- Graham
