I believe the code is calling "split" in a scalar context. Scalar context
returns the number of elements - not the different elements. Making "xpto"
take a list as its parameter stopped the warning message. So according to
the warning message, "split" should not be called in a scalar context.
use strict;
use warnings;
sub xpto(@) {};
xpto( split(/\n/, "fv\nfg" ) );
