Will factor variables support different coding schemes like indicator

A question that I have, too.  The coding schemes, at least those that interest
me most, such as reverse Helmert, can easily be done from conventional dummy
indicators with -lincom-, afterward.  The Web page does mention, "Factor
variables are integrated deeply into Stata's processing of variable lists,
providing a consistent way of interacting with both estimation and
postestimation commands."  Maybe the new -margins- can do this sort of thing,
too; I'll find out later this month.
