Assuming that the array has been converted to a scalar, then the
following "Lookaround Assertion" works:
#!/usr/bin/perl
$_ = 'a a a b b c c';
1 while s/\b(\w+) \s (?= \1\b ) //gxi;
print $_, "\n";
The scalar can be reconverted to an array.
Not sure if this is any faster.

Well I don't think I can make up a better explanation than
Gosh.. what ever happened to good ol' grep
my %seen;
@uniq = grep !$seen{$_}++, @array;

Hé ! Jenda
this slice thing is really very nice.
@hash{@array1}=@array2;
I saw it many times used in constructor of "Object Oriented" Perl's code.
Could you explain sequencely the syntax please ?

i`m not quite shure because i`m a newbie to, but
try using some RegExp like tr///
and dont forget that tr// and s// have many more functions ex. using the
(?). The book that i find most explainable about RegExp is Beginning Perl
from Wrox Publishing.

In this situation, I usually use a hash instead of an array so I can
create highly

Can anyone tell me the best method for removing duplicate array values.
eg:
@array = qw( a a a b b b c);
becomes after some operation I cant seem to figure:
@new_array_or_same = (a b c);
