> Currently the {{PropertyState}} contract specifies that an {{IllegalStateException}}
gets thrown if a single-valued property is accessed as a multi-valued one (and vice versa).
> This leads to cumbersome if statements in code that simply wants to go through all the
values of a property. To avoid that complexity it would be useful if, instead of throwing
an exception, the {{getValues()}} method simply returned an iterable containing the one value
of a single-valued property. A client that wants to explicitly check that a property really
is multi-valued can still do so simply enough by calling the {{isArray()} method.
> A somewhat similar case can be made also for {{getValue()}} on a multi-valued property,
but that's a bit trickier so let's leave it outside the scope of this issue.
