Variables at the top-level are local to the file. If you `require` or
`load` the file, the variable won't leak to the caller scope. The parent
code, in particular, can have its own `new_db` variable and do not worry
about loaded files messing with it. That is the point of the file scope.

You need to define that logic in some global place, using a global
variable, a constant, method in a module defined normally (not my_module =
Module.new) , etc. The choice depends on the purpose of that file.
