Hi,

I'm probably just being dense here, but how do you convert Array#| to a
Proc object?  I tried this in irb:

irb(main):002:0> [].|.to_proc
ArgumentError: wrong # of arguments(0 for 1)
        from (irb):2:in `|'
        from (irb):2
irb(main):003:0> ([].|).to_proc
ArgumentError: wrong # of arguments(0 for 1)
        from (irb):3:in `|'
        from (irb):3

Thanks,
Emil
