I can't see how it would break, unless we did it wrong... > If I'm wrong about that, then by all means let's use some perl Magic > (that's a technical term) to achieve this.

There might be a more gutsy way to do this so that 'ref' gives you back what you expected (would that be 'ARRAY' or 'SCALAR' ?), but there is a simple pure perl solution using overload: package PLPerl::ArgArray; use overload '""' => \&to_str; sub new { # note we bless an arrayref here instead of the usual hashref so # you can use this 'object' as a normal array return bless([@_], ... ); } sub to_str { my $self = shift; # yeah this is not right not correct :P # we could also die here with something like "You are trying to use an Array as a string" or whatever return join(',', map { '{'. $_ .'}' } @{$self}); } --------- -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
