How would one store the Property objects in the

You don't, not like that anyway. The attach call is the ruin of
it. If it was all one definition, you could use something like
std.typecons.Tuple, but multiple calls to attach need to be a
runtime function, which means what you attach will lose the
compile time type when you get it.
Best you could do is something like pc.text!string which checks
at runtime and throws if you asked for the wrong type, which is
basically just a Variant[string].
You can't use something like an array because the two
Properties are of different types. Do you really need to do
something like make a member of PropertyCollection for every
type of Property you are interested in storing and using static
ifs to determine which variable it goes into?
That would work. You could write a plain struct definition and
then the attach could be implemented as a allMembers/getMember
assignment loop, similarly to this:
http://stackoverflow.com/questions/31993705/d-call-a-function-using-a-string-variable-with-its-name/31996526#31996526
but looking at data member assignments instead of method calls.
The attach would still check the type with a throw at runtime,
since the member name you use is also a runtime thing.
