I like the idea of ARC classes. In fact I'm trying to develop an
implementation that is fully backwards compatible (currently only in my
head though :P )

They can be switched on using a compiler directive (AFAIK $ZeroBasedStrings
On/Off) in both current Delphi and FPC (2.7.1).

> In fact I do like dropping "with"  But this breaks any backwards
compatibility. So I don't complain but just don't use it. (There is a
decent way to implement "qualified with" blocks, but I don't think it is
worth the effort.) In the end, the compiler should be smart enough to
create the same code whether or nor not "with" is used.

It would be a possibility to implement a modeswitch which switches of
"with". Regarding same code: Will not be true if the the expression inside
the with-header is not side effect free.
