Maybe it's my age but I don't like dropping out of routines like this preferring a one way in, one way out approach.

begin();
do_stuff();
end();

sub do_stuff {
    my status = stuff();
    if (status is ok) { more_stuff(); }
    return status;
}

then taking this a little further, make sure that stuff() and more_stuff() return status values

begin();
do_stuff();
end();

sub do_stuff {
    return stuff() and more_stuff();
}

Real code tends to be more complex than this and sometimes it is cleaner to take the short cut.
