Because in most cases, variable names contain references for the sake of
efficiency. To get the behavior you want, try:

base_name = "" + line

But this is by no means the best thing to do in a lot of cases.

That's because base_name is an alias or something.

Really? How do you split the records after not providing the record
separator character in the saved data?

In a tab-separated database, tabs separate fields, and linefeeds separate
records. Neither tabs nor linefeeds are allowed within the fields. If you
remove either the tabs or the linefeeds from the database, you destroy the
integrity of the database.

It's okay. At the moment, you don't know enough to make an informed judgment
about Ruby. When you do, you will like it.
