Q. about validating/formatting user input

In Cocoa/ObjC there is this concept of NSFormatter, which both 
validates user input from a text field, and also formats display of the 
content. Is there any similar thing in Rev?

In Rev, what I am thinking about doing is using the keyDown message and 
regex matching to validate the input and allowing or disallowing the 
keystroke that way. However, how can one extent that to entire classes 
or textfields. Seems like it would involve a property and using the 
message path, and I have an idea, but haven't been using rev long 
enough... what's the most elegant way to do this?
