Yes, or "1 while (<$s> ne '')" which is listed as an example for
a kosher way to use a constant to express no-op in void context ;-).
=head2 No-ops
X<no-op> X<nop>
Perl doesn't officially have a no-op operator, but the bare constants
C<0> and C<1> are special-cased to not produce a warning in a void
context, so you can for example safely do
1 while foo();
