Hello all,

I have a string that is equal to:

my $str = Hello world a[0]! a wonderful experience.

And I need to replace all occurrence of a[0] to a random number from a map. So what I do is the following:

 my @arr = ("a", "a[0]", "b", "b[0]");

I have a map that maps each of the above variables to a random number. My problem is when I try the following:

foreach (@arr) {
              $str =~ s/($_)/random{$1}/g; #where random is my map}

Non of the a[0] gets replaced with its value from the map, instead with the value of a. Any idea how to fix this in perl?
