Add single-term prototype
The C<+> prototype is a special alternative to C<$> that will act like
C<\...@%]> when given a literal array or hash variable, but will otherwise
force scalar context on the argument. This is useful for functions which
should accept either a literal array or an array reference as the argument:
sub smartpush (+@) {
my $aref = shift;
die "Not an array or arrayref" unless ref $aref eq 'ARRAY';
push @$aref, @_;
}
When using the C<+> prototype, your function must check that the argument
is of an acceptable type.
