This only works because the arrays don't contain a string
with
$" as substring.
However, if you have
@current = ("foo bar", "baz");
@wake = ("foo", "bar baz");
then both
"@current" eq "@wake" and
@current == @wake.
Also, it's not clear what to do when the arrays contain
references. Should the references be the same, or is it
enough if they point to comparable data? That is, are
the following arrays equal?
@array1 = (1, [2]);
@array2 = (1, [2]);
