RE: [sv-bc] enum value uniqueness

I do not think this is legal. An enum is not a scope. The enum lablels
like 'IDLE" are created in the surrounding scope. The second enum
creates a duplicate symbol in the scope, which is illegal. 
 
You could put these in different packages, but not in the same scope.

	Hi, 

	Should the following be legal? 

	enum_logic [1:0] {IDLE ='0,START_XFER,WAIT_DONE} xfer_state; 
	enum_logic [1:0] {IDLE ='0,START_REQ ,WAIT_ACK } req_ack_state; 

	What about this? 

	enum_logic [1:0] {IDLE ='0,START_XFER,WAIT_DONE} xfer_state; 
	enum_logic [1:0] {IDLE      ,START_REQ, WAIT_ACK }
req_ack_state; 

	Thanks, 
	Shalom
