Also can we consider that put some special argument in some special
position.
The main problem data, which often be the criteria of function dispatch,
similar to OO's method target object, can as first parameter or after the
missing process parameter?
So we can have a consistent parameter order
I think the tradition is more general: abstract process which need missing
process passed in(seems all high order functions under this category)
should have missing process comes first as it's parameter.
This tradition not only limited to sequence parameter.
