[Ruby] eval question

[James Moore]

Is irb confusing the issue?

irb(main):001:0> eval "x = 'y'"
=> "y"
irb(main):002:0> x
=> "y"

But:

(in el.rb)
eval "x = 'y'"
puts x.inspect

C:\rx\rfs>ruby bin/el.rb
bin/el.rb:2: undefined local variable or method `x' for main:Object
(NameError)
C:\rx\rfs>ruby -v
ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-mswin32]
