[Moose-dev] keyed properties

Wouldn't it be useful to be able to specify properties to be keyed when they are multivalued? This would allow us to generate dictionary related code for those keyed elements; and en plus give us a way to specify that one of the properties can not be used twice within a same environment. Example usage would be the classes property of a fm3.Package which would be keyed by the property name. Like this we would be able to do something like: aPackage.getFromClassesAt("aName") instead of having to loop over the classes until we find the right one. I know that Adrian just stores all fm3specified packages+classes into one big dictionary... but of course; having this property would also enable its use one level lower. Just a thought. Toon
