Keep in mind that using load keeps local variables local to their scope
within the file:


tc@tc8 ~ $ cat foo.txt
a = 5
@b = 10

tc@tc8 ~ $ irb
irb(main):001:0> load 'foo.txt'
=> true
irb(main):002:0> @b
=> 10
irb(main):003:0> a
NameError: undefined local variable or method `a' for #<Object:0xb7d37970
@b=10>
