Well, I've been working on what will eventually become oscript v2.0 for a little while now, and while I'm not quite ready to call it done, I have setup nightly snapshots of the trunk so you can have a go at it:
https://icandy.homeunix.org/snapshot/
Version 2.0 is concentrating on new ObjectScript features and performance. Major features that have been implemented and merged to the trunk so far:
+ iterator for loop syntax: for( var o : set ) ...
+ mixin "mixes in" an object into the current
scope/object
+ regular expression suport modeled after
JavaScript 2.0
+ java Map/List object access using array index
syntax (a java.util.Map behaves as an associative
array, and java.util.List behaves as an array)
+ java object bean property access
Most of what is left is documentation, performance optimization and bug fixes.
