What's the difference between /^Foo/s and /^Foo/?

The second would match Foo other than at the start
of the record if $* were set.
The deprecated $* flag does double duty, filling the
roles of both /s and /m. By using /s, you suppress
any settings of that spooky variable, and force your
carets and dollars to match only at the ends of the
string and not at ends of line as well -- just as
they would if $* weren't set at all.
