Re: [sv-ac] New proposal for mantis #1646 - generate constructs in sequences and properties

Is that what Note 1 in the proposal is trying to get at? --

   "1. As the syntax indicates, it is required to explicitly specify
generate block within the property.  Omitting could lead to a less
intuitive code."

So within properties, although it would not actually be ambiguous to
omit the generate-endgenerate, it could be confusing, and the same
syntactic restriction is applied to sequences for consistency with
properties?

Generate endgenerate is there to distinguish property if from generate
if.

Example can be added.

What's the justification for requiring generate/endgenerate keywords
here, when they are optional in the rest of the language?

Also, it would be helpful if there were a realistic example of using
generate loops, in addition to the examples about conditional generate.

 Hello Erik,

Please find attached a corrected proposal. I did a few more
"adjustments" too. I have also deposited the proposal on Mantis.

Thank you,
