Doesn't make any sense?
foreach(a; x)
if x is not an array then a = x and the loop reduces simply and

It unifies the concepts so that one does not have to worry if x
is an array or not and can offer no harm since when x is not an
array everything simply reduces to an an alias of x.
on the otherhand some programmer might want to get informed buy
an error-msg, if he accidentally used a non-iteratable variable
for `foreach`-iteration. To avoid a silent bug
