Not everybody has a programmers mind. I don't. I have no interest whatsoever
in programming. A person should be able to use a piece of software without
having to be a programmer to do so. If a programming degree is necessary to
use Lily then it is either a) not complete enough for the general public to
use, and a warning message to this effect should be placed on the web site
home page, or b) should be aimed at a different audience -
If you use LilyPond, you are a programmer. LilyPond is a programming language*.
It has sequences, loops, nested structures, variables.
It follows a syntax and gives you a result. Do not follow the syntax
and your output will be faulty or inexistent.
