Try LilyPond.

       A further convenience can be the ‘list splicing’ operators 
address@hidden and
    address@hidden for inserting the elements of a list in the surrounding 
context.
    Using those, the last part of the example could have been written as

         …
         { address@hidden }

       Here, every element of the list stored in ‘newLa’ is taken in
    sequence and inserted into the list, as if we had written

         { #(first newLa) #(second newLa) }
