Interesting. I wonder what parts of the grammar are not LALR(1) or a LR(1) 
compatible though. I can understand the argument that using a hand-written 
compiler will allow you to more easily extend the language, since it avoids 
the problem of maintaining consistent shift/reduce tables. In my own 
implementation, the non-terminals of the AST are represented as separate 
classes, which makes it very easy to perform any kind of recursive 
processing.
