Rails - May 2012 - Kernel#send behaving strangely with ActiveRecord attribute methods

I''m going through an weird behavior with Kernel#send and *I think* it
might
be related to ActiveRecord (I''m using Rails 2.3.11).

I have a User model that has the following fields:
  email: String
  status: Integer

(among others)

If I do:

some_arg_that_might_come_in_a_local_var = true
method = ''email''
@user.send(method,some_arg_that_might_come_in_a_local_var)
=> ''user-zuv13RyHHZkAvxtiuMwx3w@public.gmane.org''

So, email doesn''t expect the additional var (it''s an AR
accessor AFAIK, so
it should not accept any args), but it doesn''t throw the ArgumentError
exception.

The some_arg_that_might_come_in_local_var is an argument that will be
passed to certain methods that DO accept a second boolean argument, but it
happens that sometimes the method argument sent to send can be email or
status.

But if I do:
some_arg_that_might_come_in_a_local_var = true

@user.send(method,some_arg_that_might_come_in_a_local_var)
ArgumentError: wrong number of arguments (1 for 0)

I then get the exception.

Any ideas?

Cheers,

- Marcelo.
