-----------------------------------------------------------------
Looking into the details, and this is less than ideal, as builders are not used
all the time.
But in both cases there are 4 functions to express the state in values or
entities. Perhaps we should instead make those functions part of a
ToValueConverter and ToEntityConverter types that are registered as metaInfo.
If the metaInfo is not present, the default is used. This feels like a 'better'
option that expanding the number of methods in UnitOfWork.
Or perhaps the metaInfo for this should be on the UnitOfWork??

> Project: Polygene
> Issue Type: Bug
> Reporter: Paul Merlin
> Assignee: Niclas Hedhman
> Labels: unitofwork
> Fix For: 3.0
>
>
> See discussion at http://markmail.org/message/yqzezcovwieu6ev3
> Now deprecated Conversion Library has support for type-relaxed conversion
> plus a way to insert custom conversion code. New toEntity/toValue support in
> UnitOfWork don't.
> Some use-cases:
> - don't expose the whole state (eg. password hashes)
> - computed/transformed state (eg. entity state ~ value state)
> This issue is about finding additional solutions to support theses usecases
> in the toEntity/toValue mechanism.
