Re: [sv-ac] 928 Proposal Updated

Hi Brad:

I think parentheses will be useful.  A user might prefer to
write 

  (posedge clk iff enabled) or reset

in place of

  posedge clk iff enabled or reset


If we don't put the parentheses in the event_expression syntax,
we have another problem because our rule for passing actual 
arguments to untyped formal arguments is that the result of 
replacement of formal arguments with actual arguments be legal.

Best regards,

John H.
