Rails - Jan 2011 - Add syntactic sugar for array '<<' method on my own method?

I want to write a method which takes its input and adds it to an array (in
this case I am trying to abstract a session item as I think it looks
prettier to use a helper method).

For example, native in ruby we have arr:

arr = []
arr << ''item''

Is there a way I can write a method that uses the ''<<''
syntactic sugar? Been
poking around and don''t see clearly how to do this.

Just like you can write a method for assignment:

def assign_something=(value)

def <<(other)

I see, so it has to be within a class and not named....  so if I am writing
a helper method in app controller then this is weird, but now I see that I
need to make a class for what I do, so thanks, my design has improved.

Module, actually.  But this shouldn''t surprise you: it''s just
a method
like any other.

It is named.  Its name is :<< .

Yeah.  Don''t put logic in your controllers.  And remember that you can 
reopen or mix into existing classes.
