[sv-champions] Mantis 1698

Hi,

Mantis 1698 has the following:

Assuming that default clocking is not defined, the following two
examples are illegal because no clock can be inferred:
assign x = $rose(b); // illegal

always @(posedge clk) begin
...
@(negedge clk2);
x = $past(y, 5); // illegal
end

I'm in doubt about whether the first example would work even if a
default clocking is defined. It might not be illegal, but I am in doubt
about whether it would work, because continuous assignments are
triggered only when a net or variable on the right hand side changes.
Can anyone resolve my doubt one way or the other?

Thanks,
Shalom
