However this works:

property Foo[AIndex: Integer; BIndex: Integer = 0]: Integer read GetFoo;
Ouch
What then about
function GetFoo(AIndex: Integer = 0): Integer;
property Foo[AIndex: Integer = 0]: Integer read GetFoo;
And if it compiles, which of those can you call
Obj.Foo
Obj.Foo[]
And what if you make that default property....
Obj[] // ????
Those all don't compile. Even using my example above "Foo[42]" does not
compile either, so while a default parameter can be declared the
compiler won't allow the default parameters to be left out in the index
clause.
Maybe we should forbid default parameters in the index clause in
non-Delphi modes so that it's clear that this won't work?
It has no sense allowing them to be declared if they don't work, so yes.
Either that or allow them to be omitted.
