Bignum#/ should not raise ZeroDivisionError if other is zero and is a Float
Missing tDSTAR from debugging method
Fixed some logic in kwargs to not throw wrong # of arguments in a few cases.  Change keywordrestarg to store and allocate a local variable just like restarg. Mildly changed interp logic for kwargs processing
Doh.  Nixed 2.0 logic check for block arg in optimized args path
Make callsite **blah work in 2.0 mode
Remove extraneous println
2.0: If no extra kwargs assign empty hash to variable
Initial reimplementation of Enumerator#next in Java.
Complete new threaded Enumerator#next and remove old logic.
Split out abstract superclass for Nexters.
Fixes to prevent finalization from setting interrupt status.
Add option for lightweight enums and introduce Array#each enum.
Perf improve Enum#next by using SyncQueue instead of Exchanger.
20: Was erroneously marking kwargs as simple method if keywordrest was specified.  Basic interp kwargs done?
Try harder to shut down Nexter thread.

Don't look too close.
Make compiler hard fail for kwargs for now.
