Note that the current feeling in SV-BC and SV-EC is that it was a
mistake to allow omitting parentheses in non-void functions.

Hi Manisha,

 

If you look at the BNF of #928 (and the original BNF for that matter), 

 

property_instance ::=

ps_property_identifier [ ( [ list_of_arguments
property_list_of_arguments] ) ]

 

sequence_instance ::=

ps_sequence_identifier [ ( [ list_of_arguments
sequence_list_of_arguments] ) ]        

 

 

it appears to me that the () are optional.  Of course, it could be
written this way for the case of a property/sequence that does not have
any arguments at all, but that was not my interpretation.  I think they
should be optional like void functions, etc.

Hi,

 

As we were discussing in the meeting if the tasks or functions require
empty '()' in all cases or not. Here is what LRM says about it:

 

12.4.5 Optional argument list
When a void function or class function method specifies no arguments,
the empty parenthesis, (), following
the subroutine name shall be optional. This is also true for tasks, void
functions, and class methods that
require arguments, when all arguments have defaults specified. It shall
be illegal to omit the parenthesis in a
directly recursive nonvoid function method call that is not
hierarchically qualified.

 

It is hard to draw a direct conclusion about sequences/properties.
Should they be treated like void functions and therefore empty
parenthesis be optional ?
