The thing is that I can easily imagine the Delphi devs to be so
stoned to use the "[...]" for static arrays inside dynamic arrays
as well which could lead to constructs like the following because
they forget that dynamic arrays could be part of static arrays as
well:
=== code begin ===
var
v: array[0..2] of array of array[0..2] of LongInt = ([[1, 2, 3],
[4, 5, 6]], [], [[7, 8, 9]]);
=== code end ===
Yes, I have absolutely no confidence in the Delphi developers.
Sometimes they have fantasy ^^. Don't underestimate them, I am sure
they can do something more unexpected ;) For NewPascal mode I see this
like :
var
v: array[0..2] of array of array[0..2] of LongInt = ([(1, 2, 3), (4,
5, 6)], [], [(7, 8, 9)]);
That is at least what I would *expect* for Delphi as well. And no, I'm
definitely not underestimating their ability to come up with strange
syntaxes... Do I do prefer not to think about it too much to avoid
nightmares :P
I don't want to use a modeswitch for every tiny little bit of
feature. What we could do however would be a modeswitch for a
strict Delphi mode that prohibits extensions and code that does
not work in Delphi (like global operators and global generic
functions). This could be used for code that is shared with Delphi
to avoid potentially breaking compilability with Delphi if one is
mainly using FPC for testing.
IMO potentially breaking compatibility is better than lock/prohibition
for missing features in Delphi (or waiting for Delphi implementation).
Programmers are not stupid and most of Delphi users knows what Delphi
have and what can be potentially risky. We have tons of examples which
should be disabled in Delphi mode but it works for comfort. r39045 is
for sure not comfortable IMO without real important reason, but this
is just my opinion.
I've decided to lift the restriction again in r39078. Happy now?
Regards,
Sven
