Re: object-model: Return by value, reference or pointer? (or something else?)

How about returning a pointer to an empty string (zero length) at some fixed
address (eg. allocated statically), which is good enough for most callers,
but provide a function or symbol that compares against that address?

This way you'd get an empty string back; if you care whether the property
really exists you do a call to noProperty() or something like that.

Regards,

Phil
