When writing Ruby you have the option to end the file early with
END. Anything after the END is assigned to a constant called
DATA which is available within the file.
I recently tried using this in Rails and it didn’t work. Instead I get
an uninitialized constant exception. Anyone know why?
Has it been disabled in Rails?

The DATA constant is only created for the running script. Thus,
require’d files do not get the DATA constant.
see the following:

[email protected]:~ $ cat d2.rb
[email protected]:~ $ ruby data.rb
[email protected]:~ $ ruby d2.rb
