Re: [Objectscript-users] retrieve full package from Value

[Rob C. <ro...@ti...>]

ok, sounds good... I think, start by having a look at  
AbstractReference (sorry, not AbstractValue, I typed too fast)... you  
can use this to create a "proxy" for the actual script package Value,  
which contains the additional information about how it is referenced.
