Hi,

wantarray() returns true if the context of the actual subroutine
expects a list as return value(s).
sub do_something {
my $arg = shift;
do_something .... and stuff it in @some_array
return wantarray ? @some_aray : $some_array[0];
}
@array = &do_something($arg);
Result: @array contains @some_array
$array = &do_something($arg);
Result: $array contains first element of @some_array
