Subject: eval and local variable


Hi,

in following script

eval "foo = 'bar'"
p local_variables  #--> ["foo"]
p eval "foo"       #--> "bar"
p foo     #--> foo.rb:4: undefined local variable or method `foo' for
#<Object:0x2ac38ce0> (NameError)

Why can't use foo variable directly?

Whereas in irb

# irb
irb(main):001:0> eval "foo = 'bar'"
"bar"
irb(main):002:0> p local_variables
["_", "foo"]
nil
irb(main):003:0> p foo
"bar"
nil
