- handling of access to private methods/fields/properties
- general missing property/method handling (order of lookup, what extension points)
- are invokeMethod and get/setProperty on GroovyObject still needed? What was their purpose in the first place and how did they develop?
- How does EMC allow extension to invokeMethod and get/setProperty logics? (see for example http://groovy.codehaus.org/ExpandoMetaClass+-+GroovyObject+Methods) And should that be kept, or is it intelligent to do so?
- How to isolate meta class registries? Is that a good thing, is it not needed? How does for example Ruby handle this?
- How easily give any created and not yet created meta class a change? How to isolate such actions?
