A concurrent-iterator is a kind of "parallel for".
---8<---
concurrent_iterator :on_value => "a, b, c" :to_field => "f" do
participant :ref => "toto"
end
--->8---
is thus equivalent to
---8<---
concurrence do
sequence do
set :field => "f", :value => "a"
participant :ref => "toto"
end
sequence do
set :field => "f", :value => "b"
participant :ref => "toto"
end
sequence do
set :field => "f", :value => "c"
participant :ref => "toto"
end
end

Something more useful maybe :
---8<---
concurrent_iterator :on_value => "employee, assistant, boss,
employee", :to_field => "target" do
participant :field_ref => "target"
end
--->8---
which is equivalent to
---8<---
concurrence do
participant :ref => "employee"
participant :ref => "assistant"
participant :ref => "boss"
participant :ref => "employee"
end
--->8---
You will find many example at : http://openwferu.rubyforge.org/patterns.html

Oh thanks. Yes, there are many many possibilities :)
