GADT properties seem to work (untested) * Property has been converted to a GADT, and will be Property NoInfo or Property HasInfo. This was done to make sure that ensureProperty is only used on properties that do not have Info. Transition guide: - Change all "Property" to "Property NoInfo" or "Property WithInfo" (The compiler can tell you if you got it wrong!) - To construct a RevertableProperty, it is useful to use the new (<!>) operator - Constructing a list of properties can be problimatic, since Property NoInto and Property WithInfo are different types and cannot appear in the same list. To deal with this, "props" has been added, and can built up a list of properties of different types, using the same (&) and (!) operators that are used to build up a host's properties. 2015-01-25 02:38:10 +00:00			`installed :: Property NoInfo`
