in thread DBI SQL adding array of values

Your concern is without foundation. The behaviour of the == operator applying a scalar / numeric context to both of its operands is not going to change in perl 5 and will not in perl 6 either. Feel safe in knowing @data == @table is unambiguous and is not going to change on you.

Also, the question of comparing two arrays for equality is more complex than you appear to think. If you'd like to hear more about equality, speak up. In a new SoPW about the different meanings of equality in comparing two arrays. Its a bigger subject than a single response to an unrelated thread merits.

    I am actually well aware of the complexities of testing for equalities in arrays. But I have also used (admittedly archaic) scripting languages where array1 == array2 tested for byte-length equality, or where the same tested equality for all elements. Either of those cases were not what the OP was looking for, but for a "number of elements" comparison.

    It is, however, nice to know that there are no plans to alter the current behavior of @array1 == @array2 in Perl 6; thank you for that nugget.
