I am always reluctant to add new keywords or methods to
core classes. Using require 'English' (which I wasn't aware
of) is reasonable in this case, although I would argue that
$0 is nearly useless as-is, and so should be aliased.
Having a perl background shouldn't be a prerequisite for
using Ruby.

Adding in_main_file increases the total complexity of Ruby,
which is already a bit more complex than I would like. Just
my own preference.
