As a conclusion, you will have compatible behavior when you use
blk.yield (new method in 1.8) instead of blk.call.
----------------------------

I'm sorry... I don't understand.  Will blk.yield do the same thing that
yield did?  Is blk.call going away, or will it still do something different
from yield?  And finally, what is the difference between blk.call and
blk.yield?
