closure, isn't it? yes it is helpful.

well the idea is not to eliminate function arguments but pass only
args specific to the fun.

also, please note that process dict allows overriding. I was thinking
more in terms of static var - same as in function scope.

Well it only takes a util fun to explicitly allow or disallow
override. Can even raise a stacktrace to show where in the code the
var was set.


why didn't I ask a while ago..
