You didn't happen to mention... is it the case that the list of input parameters for your "fullname" function happen to be the space-separated tokens that make up the full name?

If that's what is being passed to the funcion, then it would be much simpler to add periods as needed before joining the parts together: 

sub fullname {
    my @parts = @_;
    for ( @parts ) {
        $_ .= '.' if ( /^[A-Z]$/ );
    }
    return join " ", @parts;
}
