- 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?

Autohandlers/methods/attributes/inheritance

- How can I tell Mason to use autohandlers or dhandlers when calling one component from another component (i.e. internal redirect)?
- I added a simple autohandler to a directory and now my pages don't appear.
- 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?
- When using multiple component roots and autohandlers, does every autohandler in every root get called, and in what order?
- After upgrading, I see this error whenever I load a page: "The following parameter was passed in the call to HTML::Mason::Component::FileBased->new() but was not listed in the validation options: create_time"
- When I try to start my server I see an error like: "The resolver class your Interp object uses does not implement the apache_request_to_comp_path' method.
