Yes, I didn't expect my mails will suddenly change your opinion. And
even if they would change there are enough fpc team members who will
protected objfpc generics :) I only hope to stop duplicate
implementation of other delphi features.
I won't remove your hope, but I'll also not do anything to fulfill it :P
And regarding backwards compatibility: we are not only talking about FPC
and Lazarus. There are enough people around that use FPC's generic
syntax and that alone is reason enough to keep it.
Enough - how much? 50 or 100 projects? What will be needed to make
them work with dephi syntax? Remove word generic and specialize?
Once we support generic functions/procedures (which Delphi does not
support) it will be more :)
Especially those that don't care about
Delphi compatibility. Also it seems that those that like to develop in
Delphi are the only ones complaining...
Think about component and applications developers who need to care
about FPC and Delphi. Less incompatibilities FPC will have more 3rd
party components and applications it will get.
For exactly this purpose we have the mode Delphi. And if something is
not working there it's either a missing feature, a bug or something that
we just plain refuse to support... (e.g. in Delphi you can have one set
element multiple times in the same set constructor: [objectdef,
objectdef, objectdef])
I remember author of Total Commander who had failed to port his
project to FPC + Laz because of many incompatilities in both projects.
And some differences are by design. Think about resource string handling
here. We might provide the LoadResString function/callback, but it's
just a dummy, because FPC's resource strings work differently. The same
for Lazarus: some differences are by design, because Lazarus is not
fixed to the Windows platform (as a Lazarus developer you should know this).
I remember Fib+ developer who stoped his effort to port component to
FPC after some found incompatibilities.
There is nothing good in incompatibilities.
As already wrote by Michael and me: it's not the purpose of mode ObjFPC
to provide compatibility.

Sven
