actually seems slightly weaker.

So remove it for now.

Declare function under local namespace. This removes a
warning from the picky Intel compiler.

853ce65f17 Group common evaluate code 
This removes code redundancy but perhaps
impact performance due to uninlining.

Testing for regression is needed. For now
aim to best code readibility.
