Fixing warnings 'n other stuff

[ #15542 ]

:(

sub convert_to_list {
    my $self = shift;
    my @args = split / -/, $self->arguments;

    my $first_arg = shift @args;

    @args = map { '-' . $_ } @args;
    unshift @args, $first_arg;

    return @args;
}

sub convert_to_list {
    my $self = shift;
    return () unless $self->arguments;
    return split / (?=-)/ $self->arguments;
}

I love Perl :)

    • In theory, that looks good and if I were calling the shots, it would be. However, consider the following:

      some_func(other_func1(), other_func2());

      If one of the "other funcs" has a bare return, some_func() will be passed a list with only one element! You can get around this by prepending the function calls with scalar, but that is not done in the shop I work at, yet function calls are often embedded in other function calls. Thus, we have explicit return values. If only one value is being returned, we

    So $self->arguments returning "0" needs to be ignored?
