A local variable to the block, used to pass the parameter from File.new.

Doesn't Smalltalk use vertical bars as well? I don't think that
qualifies as line noise. The @-prefix on instance variables might,
and I'll admit to not liking that very much when I first saw Ruby.
However, most Java or C++ programs I've seen tend to use *some* sort
of naming convention for instance variables, either myFoo or _Foo or
something like that. Given the choice between myFoo and @foo, I'll
take @foo.
