You could do this pretty easily with a not-so-fancy fancy session
manager process. Since you're actually specifying the Params that you
want to pass and only preserving those, you don't even need
continuations to do it (unless you're hoping to resume inline, which
it doesn't look like you are).
If you are hoping to resume inline, you could simulate it with
something like:
%% prepare the continuation
session_manager:new(Params,fun(MoreParams) ->
%% additional processing....
{ewc, controller, function2, [results_of(Params,MoreParams)]
end
end),
%% and return the intermediate result
{ewc, controller,function,[foo]}.
