Can you explain this ? As far as I know, there no member of the core team

I was obviously generalized a bit too much. If you really want me to,
I can search the mailing list archive to find out who said what.
Anyway, it was told many times before that inspecting a property with
Getter and Setter methods may change underlying data - so the whole
debugging of Properties are frowned upon.
I'm simply stating that developers should know what they are doing,
and that I have never seen a Delphi developer ever complain about that
"possible data change" issue. It's only FPC developers that keep
mentioning it.
IIRC that is mixing up 2 things. But in Graeme favour, likelihood has
it, that others have mixed it up before: so this may have been said the
way quoted (but not necessarily by people people listed)
IIRC there are several technical underlying issues (but I may be wrong):
like not yet implemented to call functions from the debugger at all; and
issues to represent the same symbol as getter and setter with the means
of stabs/dwarf ?
The "accidental change" is more an argument, to have the function off by
default.
And true, no one ever complains about having had that problem. Those who
do have it are often beginners, they have no idea what it is, they blame
it on their own code, and since they can't name it, they can't blame it.
(IIRC that was my own experience too, a long time ago, in a galaxy right
here)
[if any one feels the need to answer this last one: do it on fpc-other,
or in private mail to me; or I get in trouble for having written this]
