There's also the question of what you mean by compatibility: Very advanced tweaks usually rely on the way lily's internals are organised, which may change over time. Since lily contains a Turing-complete programming language, for some language updates it is thereby _impossible_ to create a script that upgrades _all_ .ly files perfectly.

Actually, doesn't this mean that we can _always_ upgrade _all_ .ly files perfectly? Since lily contains a Turing-complete language, we just need to write a universal Turing machine which emulates the behavior of 2.4 (or whatever). Then convert-ly takes 2.4, adds our Turing machine, and presto, we have a .ly file which compiles under 2.8.

Of course, that .ly file is probably about 20 megabytes in size, and would take a huge amount of time to run... but it would work! :)
