Re: [sv-ec] foreach iterates over unpacked arrays

Dave,

Your proposal for http://eda.org/svdb/bug_view_page.php?bug_id=1306
mentions about the changing of size of a dynamic array dimension while
iterating over it with foreach, but not about the changing of entries in
an associative dimension.

Thanks. I am enjoying my week of fame.

What I was trying to say about queues was that the text was cut and
pasted from Vera, which had no packed arrays or queues at the time. So
any type of array is legal.


I am rewriting the proposal, trying to come up with a description for
fact that you don't need commas (,) at the end of the list to indicate
omitted variables, but I don't see that wording anywhere else. Is the
BNF sufficient? I would have thought it would have been there for lists
of port connections, or lists of arguments for tasks, functions.

Also, I'm assuming if the user changes the size of the array during a
foreach, the results are undefined and may cause an illegal index value
to be generated.

Dave
