Subject: [ruby-core:20550] ruby -p behavior in 1.9

Hi --

Is this expected/correct behavior for 1.9? (Today's SVN head.)

david-blacks-macbook:~ dblack$ ruby19 -pe 'gsub(/a/,"b")'
a
-e:1:in `<main>': undefined method `gsub' for main:Object
(NoMethodError)

david-blacks-macbook:~ dblack$ ruby19 -pe '$_.gsub(/a/,"b")'
a
a

david-blacks-macbook:~ dblack$ ruby19 -pe '$_.gsub!(/a/,"b")'
a
b

In other words, only gsub! with an explicit $_ has any effect.
