correct in believing that something like
type t1= array of integer;
var a1: t1;
x: integer;
a1 := [1,2,3,4,5];
can't be done at present, irrespective of any custom definition of
the := operator?
Maybe if you overload the assignment operator for "t2=set of byte" to
"t1" assignments, but I'm not certain. It's definitely not something
we explicitly support.
That's a good point, although obviously ordering would be lost. After
I'd tinkered with it for a while I concluded that it was probably
related to the discussion of tuples a few weeks ago.
Not really.
Also the principial components are already available in the compiler so
in theory (!) one could implement this. Array constructors (the "[...]"
notation) is already used for open array parameters and array
initialization is already possible for named dynamic arrays in the form
of the delphi compatible "TMyDynamicArrayType.Create(1, 2, 3, 4, 5);"
(yes, I think this is a bad choice of implementing it and comes probably
from Delphi.NET :( )
