Hi,
I've seen a lot of examples in Rails code where they're accessing what appear
to be instance variables from self. Something like
self.foo = true
Now, I'm assuming that you can only access methods this way, so this is
actually a method call of
self.foo=(true)
Is that right? I'm not always clear on it.
Thanks,
Mike

And you're also apparently a bit confused about what's really happening.
self.foo = true
becomes:
self.foo=(true)
which typically implies something like:
def foo=(foo)
@foo = foo
end
But you probably are more used to seeing something like:
attr_accessor :foo
which sets up the "def foo;@foo;end" and "def foo=(foo);@foo=foo;end" for you.

That is correct.
