The line blurs, though:
($a, @b, $c) = (1 .. 4);
It may be meaningful to draw a distiction between array and list
assignment, but only if the former is considered a subset of the latter.
Then one could define a list assignment as a series of scalar and array
assignments, noting that an array assignment can only exist within a
list assignment, while a scalar assignment can exist alone. (Or,
alternately, that a lone array assignment is equivalent to a list
assignment where the list contains only one array. Yes, this is an
example of those funny unflattened lists like the one in "\(LIST)".)
The Nit Protection Society, however, is protesting this discussion...
