PECL::Parse_Tree is still in alpha state and has not been updated since 
January 2007, so I don't have too much confidence in it being 5.3 compliant.
For now I've opted to approach this from the Java side using DLTK and 
PDT which is very powerful and fast. Plus, it is my hope that - PDT 
being a widely used PHP IDE and all - the parser will always be fairly 
up to date.

At this point it's only a little side project. Eventually, I hope to 
build some sort of PHP precompiler for our CI server that can help us 
with QA and such (e.g., checking pre- and postconditions). It is in a 
way very similar to AspectPHP, but may very well go beyond what is 
possible with AOP (at the cost of being not as flexible, obviously). But 
again, this project is still in a very early stage; I'm just writing the 
very first prototype to see how far DLTK can take me.
