[vhdl-200x-ft] Question on aggregates

Hi,

Please find below some examples of aggregates that are, I think, not legal
in vhdl 87 and 93.
Do you have intention to allow those kind of codes in the next vhdl
standard.? I think, It would be nice .

CASE 1)
procedure (b,c : out signed)
begin
   b :=(OTHERS => '0'); -- not legal because b is unconstrained
   c :=('1',OTHERS => '0'); -- not legal because b is unconstrained
end;

--------------------------------------
CASE 2)

generic n : integer := 3;
...
signal a : unsigned(n downto 0)
constant b : unsigned(n downto 0) := ('1',OTHERS => '0'); -- not legal
because n is not locally static
...
a<= ('1',OTHERS => '0'); -- not legal because n is not locally static
--------------------------------------
CASE 3)
signal pos : integer := 3;
signal a : unsigned(7 downto 0)
...
a<= (pos => '1',OTHERS => '0');
--------------------------------------

Kind Regards,
Yannick
