class LHoistNonunique

extends Lens

Hoists (see LHoist) a property from among others, merging its sub-properties into the root tree. On putback, a supplied predicate identifies properties which belong to the grandchild, so that those properties can be putback appropriately.

Note that the property must be object-valued; anything else won't be able to merge with the rest of the root tree.
