Regarding NR 6.7, the current text is misleading (if not wrong). It says
that
"|\tweak| doesn’t behave like an articulation regarding the syntax"
but in fact you can use
c-\tweak #'font-size #-3 \flageolet
What's correct about the current formulation is that you cannot use
c^\tweak #'font-size #-3 \flageolet or c_\tweak #'font-size #-3 \flageolet
However, this is not the problem with the example shown in the manual.
There, the syntactic problem appears in the attempt to define the macro F
and is rather related to the syntactical limitations of what you can do in
a macro definition.

N.R 6.7 shows the use of Scheme code as an articulation. The reason why
this works is unclear to me, but I can see there is some power here. An
explanation would be really helpful. The articulation that is added
is not
a Scheme function, but rather the return part of a Scheme function.
An articulation is represented by a Scheme expression (not a Scheme
function):
(make-music
'ArticulationEvent
'direction
1
'articulation-type
"flageolet"))
Here, a Scheme function is used, which constructs such an expression.
These things are pretty
common in the world of Scheme and similar languages. I once worked
with a huge program
implemented in LISP, where the program constructed new LISP
expressions, which were
evaluated and in their turn constructed new LISP expressions which
were evaluated ...
and in the end returned something. I can honestly say that none of us
at the company understood
fully how that program worked, but for some weird reason it seemed to
work fairly well anyway.
