Sure. I personally agreed with the comment, but I would not vote 'no' because of it. The only use in the BNF of actual_argument is in assertion constructs, so you can't appeal to other parts of the BNF for precedent or consistency.

If we introduce new terminals for all possible use cases, the BNF will become completely unmanageable. I think this issue should be discussed by all committees to elaborate the common methodology. I don't feel comfortable to such changes at the last minute.

The use of "actual" is confusing. By your argument, sequence_actual_arg is also inconsistent with tasks and functions, which use simply 'expression'. Note for example that there are many types of 'identifier' that all reduce to 'identifier'. For example, array_identifier ::= identifier block_identifier ::= identifier Each is used where the semantics match the name, even though they are syntactically identical. array_identifier is not used for blocks, and block_identifier is not used for arrays. On the other hand, 'identifier' and 'expression' are generic names with no semantic information about where they are used. They could be used anywhere they are syntactially correct. But if you use a name that has some semantic meaning, then you should not use it where the meaning does not match its use.

Dmitry From: Bresticker, Shalom Sent: Tuesday, April 14, 2009 7:57 AM To: Korchemny, Dmitry; sv-ac@server.eda.org Subject: RE: feedback to P1800 WG on ballot issues Hi, 87 - Mantis 2649: sequence_actual_arg is used to represent the default argument SV-AC believes that there is no added value in introducing a new non-terminal identical to sequence_actual_arg. It would also introduce an inconsistency between the BNF of sequences on the one hand, and the BNF of properties, functions, and tasks on the other hand. Therefore SV-AC recommends to leave the text unchanged. [SB] Why would this be inconsistent with tasks and functions? Tasks and function BNFs use simply "expression" for default values. Module port defaults use "constant_expression". Neither uses "actual" for "default". As for properties, yes, the same problem exists in the property BNF. I personally agree with the comment, though I did not submit it.
