[Grammatica-users] infinite parentheses

[Steffen Gaede]

I've following definition:

%tokens%
...
LEFT_PAREN =  "("
RIGHT_PAREN = ")"
...

%productions%
...
W1 = ("(" W1 ")") | ....
...


It's running with something like this:
(bla) => "(" bla ")"

But if I've more then one parenthesis, i've got the error, although it
should be interpreted like this:
((bla)) => "(" (bla) ")" => "(" bla ")"
