Hmmm... Haven't seen a solution using the tailor-made grep.

my @array = (0,1,2,3,4,5,6,7,8,9); # The source array
my %DropList = map {$_ => 1} (2,4,6,8); # A hash of the indices to rem
+ove

my @newarray = @array[grep {not exists $DropList{$_}} (0..$#array)];

print "@newarray\n";

Notes:

• I am still using 5.005_57 to match a production server, so if you prefer to use exists on arrays in 5.6...

Enjoy.
