functionality. I have some experiments with modified helpers for types (as
aspects for classes), and what I can say now :

full potential of class/record/type helpers is not used :), and by bad

new syntax and functionalities. IIRC Sven did not want to use "with" just
for "type helpers" because it is reserved for more amazing feature like
"aspects", but when type helper has the same root as aspect (aspect as sub
kind of helper) then "with" can be used for both : "type helpers" and "type
