Nice! slightly more convoluted to make assertOk return what the passed code block returns: 
package Assert;
require Exporter;
our @ISA = 'Exporter';
our @EXPORT = qw[ assertOk assert ];


my $nTests = 0;

sub assertOk (&$;) {
    my( $package, $file, $line ) = caller;
    my( $code, $desc ) = @_;
    my( $scalar, @list);
    warn sprintf "%s %d # %s [%s(%d)]\n",
        (
            (
                wantarray
                    ?
                (@list = $code->())
                    :
                ($scalar = $code->())
            ) ? 'ok' : 'not ok'
        ),
        ++$nTests, $desc, $file, $line
    ;
    warn $@ if $@;
    wantarray ? @list : $scalar;
}
