[antlr-interest] Context-Sensitive Follow Sets.. Bug?

[Jim Idle]

I can't work out what either of you guys mean - perhaps I missed some posts,
I have been pretty busy. If you are getting reference errors to parameters
then it just means that you are trying to use local parameters in semantic
predicates and need to store the parameter in a scope and refer to the scope
instead.

The followset is a stack at runtime and you can combine the sets or use the
stack top etc. I am not sure what else you mean by context sensitive follow
sets.

Hello,

I have been looking into this as well and was wondering if ANTLR v3 supports
it.
Whenever the parser backtracks (loopbacks), the context-sensitive
information is not carried forward in the loopback, causing the parser to
complaint about reference errors for the parameters in one of my
applications.

Best regards,
