Actually, I like David's original proposal better if the semantics of 
the construction is to both typeset the particular music and to use it 
as a template for a beaming rule. If we allowed a very long descriptive 
name (and ignore any recent discussion on what naming style to use for 
commands) the function name could be \use_as_template_for_beaming and en 
example use could be:

\relative c' {
\time 8/8
\use_as_template_for_beaming{ c[ d e] f [ g a] g[ g] } |
f e d e d c d d |
\use_as_template_for_beaming{ c16 [ e ] g [ e ] f4 g[ a] g16 [ e] d[ c] } |
...
\time 3/4
\use_as_template_for_beaming{ c8 [ e g c ] g [ e] } |
...

}

This would allow the user to specify concrete example in a familiar 
syntax and at the same time save some typing. Obviously, the actual name 
of the function should be something more compact.

However, it's not exactly clear what the semantics should be, since in 
the above example, we want the beaming rules to be added to the existing 
rules, but perhaps the default beaming rules should be removed at the 
first time \use_as_template_for_beaming is used. Also, what happens if a 
user specifies contradictory rules? I'm sure there are lots of 
situations where the result would be fairly non-intuitive, in spite of 
the seemingly intuitive syntax.
