%dprec also works fine with the this, original, example.
The problem comes with '(x) + (y) + z' (which I gave as
a example on comment in this thread, rather than starting a
new thread; as if people were not confused enough).
There are four possible parses of this expression: two
of which are causing my current problem. The two
possible parse trees of interest are
+
/ \
(cast) z
/ \
x +
|
()
|
y
and
+
/ \
() (cast)
| / \
x y +
|
z

Your grammar contained a single %merge. I thought at
least two are required?
