[rspec-users] Problem with Custom matcher and Blocks

I've still been working on this, and can't figure it out.
I did see this old thread that covers a similar problem down the page a bit:
The OP eventually links to a project where it explains how to do what he was
trying to do, which is here:
So I looked through, and it seems promising, but it's still not working.
I mean that the difference is that he is doing something like:
response.should have_form('/users') do
with_text_field 'First name', 'user_first_name'
Etc. But I want to pass a variable to the block with the scope, so I want to
do something like:
response.should have_form('/users') do |form|
form.should have_text_field 'First name'
I find that more readable.
So does anyone know how I can do this?
Also, in this person's code, he passes a scope to the matcher, like:
Def have_form(action, &block)
HaveForm.new action, self, &block
And then he uses it in matches? Like:
response.should @scope.have_tag('form[action=?]', @action) do |form|
@block.call if @block
So I'm stumped. Any help would be much appreciated, as I've been working on
this for at least three days now.
