I confirm that this updated patch fixes the above example:

=> nil

10
2
=> 2

 >> f = lambda {|x=8| p x}
=> #<Proc:0x83af7c0@(irb):12 (lambda)>

 >> test &f
8
2
=> 2

=> nil

 >> test2 {|x=5,y=10,z=15| p x: x, y: y, z: z}
{:b=>#<Proc:0x83bd26c@(irb):11>}
{:x=>15, :y=>10, :z=>15}
=> {:x=>15, :y=>10, :z=>15}
