How to output data from LESS array and make rules?

Question

Less

There are 15 points with absolute positioning. The position is given as a percentage for each point.
Something like that.

.point:nth-of-type(1) {
  bottom: 10%;
  left: 20%;
}
.point:nth-of-type(2) {
  bottom: 15%;
  left: 25%;
}

How can I make an array like
$array:
10 20,
15 25,
12 45;
And then generate the rules as in the example above?
