Re: Passing Sessions with Curses::UI::POE

Check out POE::Session's postback() and callback() methods, which were created for this sort of thing.  These generate anonymous coderefs that post() or call() the invocant session.  For example:

$CUI->set_binding( $SESSION->postback("blah"), "b" );

See the docs for side effects, including numbness, shortness of breath, upset stomach, and the ability to smell concepts that can't be expressed in a single English word.
