Gratz, seems that I will need to update NewPascal soon to get this fresh
feature :).
They decide for [] probably because it is similar syntax like for open
arrays. IMO "[]" syntax has more dynamic meaning/nature so looks more
proper for this feature (as you said "()" syntax is used for static
arrays), but this is probably individual taste.
"[]" also might be better for something like this :
var
f: array of TSomeRec = [(a: 10; b: ['1', '2']), (a: 20; b: ['6'])];
instead of
var
f: array of TSomeRec = ((a: 10; b: ('1', '2')), (a: 20; b: ('6')));
The main gain of different syntax between Delphi and ObjFpc is more
troubles for Pascal Programmers. :(
Why you decide to prohibit static array constants inside dynamic array
constants for Delphi modes in r39045? I do not understand this decision. It
is some punishment for using Delphi mode? -,- IMO bad decision.
For the consequence the following code
var
f: array of TSomeRec = [(a: 10; b: ['1', '2']), (a: 20; b: ['6'])];
should be also prohibited in Delphi mode, because it not works in Delphi
like static array constants inside dynamic array constants...
