Yes, this is a corner case. If the getter is not set to return an
lvalue, that makes as much sense as trying to get a reference from an
rvalue, like &5.

That is expected behavior. Although able to emulate variables,
properties are not variables, and neither functions. They could be seen
as a collection of delegates. In some cases, the compiler may allow you
to retrieve individual delegates from the property through some syntax,
like:

	auto bar = & property(foo).get;
