Comment #8 on issue 3487 by address@hidden: Patch: Make several special  
characters with or without backslash "non-special"
http://code.google.com/p/lilypond/issues/detail?id=3487

For casual reviewers: let me point out more explicitly that this patch  
series makes _two_ syntax changes that appear mostly unrelated to the patch  
itself (the relation is by technical necessity).

Those two changes are

a) that the shorthand for staccatissimo becomes -! instead of -| as  
currently.  Taking aside the technical necessity because of | being freely  
definable including as a postevent, and thus not visible as a _character_  
to the parser, I find that shorthand making a lot more sense than the  
previous one, in particular given that -. already is staccato.  So I am  
pretty convinced that this change would be able to survive on its merits  
alone.

b) that \tempo 4. = 60 ~ 62 becomes \tempo 4. = 60 - 62 instead.  That's  
not terribly fabulous, and I am particularly considering _not_ permitting -  
into REAL tokens at all.  At the current point of time, writing \tempo 4. =  
60-62 (namely without a space between - and 62) inside of a \midi block  
will likely cause trouble.

~ was actually a rather insane character here, and indeed, the whole \tempo  
syntax is nothing to be proud of.

On their own, those changes probably make some sort of sense in a  
low-priority way.  But they are required to make this issue fly.

The value of this issue is mainly removing hardwired semantics and making  
it easier for people to experiment with extending and/or redefining various  
details of the syntax.
