4. The syntax that was introduced by Borland is not very pascalish in my

this won't simplify the parser anymore because of the Delphi
compatibility).
Delphi syntax:
TypeIdentifier = class|record helper(ParentHelper) for ExtendedType
Proposed FPC syntax:
TypeIdentifier = helper(ParentHelper) for class|record ExtendedType
What do you think? Maybe also the "class|record" part can be left out,
because this part is not saved in the objectdef and can be determined by
the compiler automatically.
I always think that if there is no need to create an incompatibility -
better to not create it. But my ideas often does not get support of
other FPC developers.
I have tought about this topic a bit more. On the one hand I still want
a cleaner syntax for this, but on the other hand I also understand that
others want to have the ability to use "objfpc" code in Delphi with as
less ifdefs as possible (or the other way round).
So what about the following compromise:
I will add my proposed syntax, but the Delphi compatible one can be
activated with a mode switch (which will be enabled by default in mode
Delphi).
And if you really insist very hard to have mode ObjFPC compatible with
mode Delphi, I can also live with the switch meaning "enable non
compatible syntax" and being disabled by default.
I plan to do something similar when RTTI attributes are implemented
(either by me or someone else) as well, so the modeswitch will have its
use there, too.
