[vhdl-200x-ft] What do you think of adding the possibility to pass a range to a function or via a generic?

Hi,

Actually it's not possible in vhdl:
- to pass a Range as a parameter of a function
- to return a Range as a result of a function
- to connect a Range to a generic

This is for me a big limitation of the actual standard. And I think, if 
it's not to complicate, it's something that must be supported in the next 
standard.

Take for example the functions Ufixed_high, Ufixed_low of the fixed_pkg, 
they could be replace by a unique function Ufixed_range.
Such that the following lines :
    variable uin1din2 : ufixed (UFixed_high(in1'high, in1'low, '/', 
in2'high, in2'low) downto
                                UFixed_low(in1'high, in1'low, '/', 
in2'high, in2'low));
becomes
    variable uin1din2 : ufixed (UFixed_range(in1'range, '/',in2'range));

Kind Regards,
Yannick
