just an idea (!! operator)

[akaz]

if needed, the operator !! (double exclamation mark) could be 
defined.

it is just an idea, i do not have any specific use in mind.
i encountered the operator in RT operating systems book:

c!!e sends the message e along channel c
c?x assigns to variable x the value from c

maybe this could be integrated with the concurrency somehow or 
used in some other area.
