Hello,
a few hours ago I got asked on IRC how one could pass non-string variables like
in
participant :ref => 'alpha', :something => "${v:my_array}"
I replied "you should copy the variable into a workitem field".

In order to make things simpler, I added a twist to the so called "dollar
notation".
If, when all the substitutions are done, the resulting text look like
"$f:xyz" or "$v:xyz"
and there is no { or }, the literal value in the field 'xyz' or the variable
will be returned, not necessarily a string.

(the tests the commit add may help understand this trick)
So it allows :
participant :ref => 'alpha', :something => "$v:my_array"
I'll probably explore the benefits introduced by this technique, it can
probably help with many expressions.
BTW, I just introduced the beginning of a :filter attribute implementation
https://github.com/jmettraux/ruote/commit/4e502306c50cd9bcfccaa858f8e62d3d776bd8a2
you can wrap a participant expression or any expression in an in/out filter.
If you have any question/suggestion/critic, feel free to fire, best regards,
