Re: Addin exceptions in SvStream

Looking at it, it reminds me of JavaCC visitors - I was expecting
something a tad bit more complex.

Since we don't have flow analysis at that level, we may have some
erroneous results, but I'm guessing we'll have accuracy in the 90%
range.

Tell me, why Clang then? Is it because the JavaCC or Antlr grammars
weren't good enough?
