Subject: [sv-ec] Questions/Issues on classes

In the process of trying to write some examples of classes I found the
following other nitty-picking problems with the current class
definition that should be fixed and should be a quick vote or
explanation.
-------------------------------
Declaration of class parameters
-------------------------------
The current syntax for class parameters in the examples is
class Foo_c #(parameter type p_t);
...
endclass
This should be changed to be like module, interface, and program
parameters:
class Foo_c;
parameter type p_t;
...
endclass
---------------------------
Declaration of 'new' method
---------------------------
None of the examples show a type on the declaration of the "new" method
class Foo_c;
function new;
enclass
Is this OK or should we require/allow a type?
class Foo_c;
function Foo_c new;
endclass
-----------------------------
Setting return value from new
-----------------------------
Is the "new" method allowed/required to set the return value?
None of the examples show it.
class Foo_c;
function new;
begin
...
new = this;
endfunction
endclass
----------------------------
Sensitivity of class objects
----------------------------
Will a change on the value of 'x' or 'x.i' wake up the following event
control?
class C;
int i;
endclass
C x;
...
@(x)
...
