    This gets my vote. I have a rule, "never use s/// when a tr/// (or y/// in this case) will do." I ran some benchmark tests a while ago on s vs tr and tr is much faster at deleting characters from a string. (This might be stating the obvious.)

      I agree with kwaping, I would use tr/// for this solution. 
      #!/usr/bin/perl -w
use strict;

while (<DATA>) {
    chomp;
    tr/[]//d;
    $_ = join(" ",split " ", $_);
    print "$_\n";
}
