RE: [sv-ec] Can foreach iterate over a queue? If not, 12.7.3 would be more user-friendly if it mentioned this restriction

But the sentence before that says

"A queue is analogous to a one-dimensional unpacked array that grows and
shrinks automatically."

Analogous means equivalent in some represents. I would also say that
"foreach" is an indexing operations


The intent is that all unpacked arrays, fixed arrays and the dynamically
sized arrays (dynamic, queues, and associative) have the same semantics
for all array operations except in those that would allocate or
de-allocate elements, and in argument passing by reference of individual
elements. Associative arrays do have a few additional methods for
traversing their indexes, but there is no technical reason in
restricting those methods to that one array type.
