key to concurrency support

3.14: adda/translation/concurrency
. the recently found scripting lang, falcon,
has good support for concurrency
-- very impressive .
. might be good code to reuse for adda;
but c++ code and with multiple authors
might be quite frustrating for a
beginner of the lang .
. it doesn't take a lot of coding
with an elegant design;
the key to concurrency
is the recent idea for coroutine translation:
every sub is converted to a coroutine
and a yield placed in every recurrence
(loops, upward goto's ...).
