The problem is that now that the local delegated property metadata is in
the $$delegatedProperties array of the containing class, the access to
it from code calling an inline function with a local delegated property
is illegal.
Currently it seems to be a lot of work to support this rather rare case
properly (see the comment in ExpressionCodegen.getVariableMetadataValue)
so we postpone it and return the old behavior of using the anonymous
KProperty subclass for metadata
