Togher with making > return value escape this probably completely disables any chance for IPA > tracking of C++ data types... Note 'this' is "escaped" anyway since it points to incoming memory. Improving handling of 'return' really _only_ helps function-local allocated storage, _nothing_ else. Which is why it wasn't priority at all as it didn't look to be enabling any (important) transforms.
