Yes, you would have a usage problem, as the package name would be passed to the function, which the function does not expect. Try this, it will become clear:

use p;

use strict;
p->abc;




package p;

use strict;

sub abc {
    print "begin params\n";
    print(join(",", @_), "\n");
    print "end params\n";
}
