I obviously have a lot to learn about about the wonders of splice with arrays.
If using your example I wanted to delete the row instead of insert a new element, how would I do it ?
I tried 
 for my $rc (@R) {
  if ($rc->[0] eq "a") {
    splice @$rc, 0, 2;
  }
}

but this just removes everything (including the line I want to delete) up to the end of the array
I also tried this 
for my $rc (@R) {
  if ($rc->[0] eq "a") {
    delete $rc->[0-2];
  }
}

This works but then when I try to print the array out I get an uninitialized value in concatenation error.
I'd expected this because the array wasn't scrunched up and delete is not the right thing to use I guess. The print I used was
foreach (@records) {
              $buf .= "$_->[0] $_->[1] $_->[2] $_->[3]\n";
              print $buf;
}
