Subject: Help with eval

Am I missing something with eval? Why does this code not work?

eval("foo = 1")
puts foo

Gives:

C:\example\trunk>ruby script/runner lib/aggregate/keith.rb
C:/example/trunk/vendor/rails/railties/lib/commands/runner.rb:45:
undefined local variable or method `foo' for main:Obje
ct (NameError)
