C<$a>. If C<$b> is negative, then C<$a % $b> is C<$a> minus the
smallest multiple of C<$b> that is not less than C<$a> (i.e. the
result will be less than or equal to zero).

+Note that when C<use integer> is in scope, "%" gives you direct access
to the modulus operator as implemented by your C compiler. This
operator is not as well defined for negative operands, but it will
execute faster.
For constructs that do interpolate, variables beginning with "C<$>"
or "C<@>" are interpolated. Subscripted variables such as C<$a[3]> or
-C<$href->{key}[0]> are also interpolated, as are array and hash slices.
-But method calls such as C<$obj->meth> are not.
+C<< $href->{key}[0] >> are also interpolated, as are array and hash slices.
+But method calls such as C<< $obj->meth >> are not.
Interpolating an array or slice interpolates the elements in order,
separated by the value of C<$">, so is equivalent to interpolating
