- Is there a syntax checker like perl -c for components?
- When I change a component I don't always see the results in the output. How do I invalidate Mason code caches?
- Mason code caching breaks down often in my situation. Couldn't you do something smarter than just comparing the timestamps?

- How can I tell Mason to use autohandlers or dhandlers when calling one component from another component (i.e. internal redirect)?

- Where does a dhandler inherit from? Can I change it to inherit based on the URL path?
- Can I change the value of an attribute dynamically, based on the request?
