quoting Damian's original mail[1]:
> uniq - remove duplicates without reordering
^^^^^^^^^^^^^^^^^^
Would not that mean the original order of the first ocurrence is
preserved? This is what Ruby Array#uniq does:
[4,1,2,4,2,3,5].uniq => [ 4, 1, 2, 3, 5]
The behavior is consistent with the description given "ri Array#uniq"
------------------------------------------------------------- Array#uniq
array.uniq -> an_array
------------------------------------------------------------------------
Returns a new array by removing duplicate values in _self_.
a = [ "a", "a", "b", "b", "c" ]
a.uniq #=> ["a", "b", "c"]
A naïve Perl 5 implementation could be:
sub uniq {
my (@u, %h);
for (@_) {
push(@u, $_) unless $h{$_};
$h{$_}++;
}
return @u;
}
