Rails - Nov 2005 - What does ActiveRecord#send do?

Apologies in advance for the newbie question...

I''ve seen usage of a "send" method on ActiveRecord objects
but I''m not
sure what it''s intending to do.  For example, scaffolding will use the 
.send method on the model object in the list template.

I checked api.rubyonrails.com page but somehow didn''t find any
specifics
about it.

Can someone explain what it''s used for?

Thanks!

#send is inherited from Object:

http://ruby-doc.org/core/classes/Object.html#M000998

These statements are equal:

@person.age
@person.send :age

@person.age = 5
@person.send :age=, 5

@person.set_age(5)
@person.send :set_age, 5

Ah!  So it''s a way to dynamically call a method given its name - very 
cool.

Thanks again.
