[sv-ec] covergroup sample method

Hi Dave:

Why would it not be legal to call a covergroup sample method from a
sequence or property?

We have

   16.10 Calling subroutines on match of a sequence

   Tasks, task methods, void functions, void function methods, and
   system tasks can be called at the end of a successful non-empty
   match of a sequence. The subroutine calls, like local variable
   assignments, appear in the comma-separated list that follows the
   sequence. The subroutine calls are said to be attached to the
   sequence. It shall be an error to attach a subroutine call or any
   sequence_match_item to a sequence that admits an empty match. The
   sequence and the list that follows are enclosed in parentheses.


I thought that the covergroup sample method would count as a
void function method.  Am I being naive?
