 Priority:  blocker             |   Milestone:

--------------------------------+-------------------------------------------
 Since the Jan. 12th nightly, macirb no longer understands blocks with more
 than one argument:

 {{{
     irb(main):002:0> h={:a => "a", :b => "b"}
     => {:a=>"a", :b=>"b"}
     irb(main):003:0> h.each{|k,v| puts k;puts v}
     SyntaxError: compile error
     (irb):3: duplicated argument name
 }}}
 (In the first few builds after jan 12, this caused a breakpoint trap)
