How does .count() operation work on Sequences? Does it aggregate all elements going through the sequence and then counts them all at the end very much like .size() in Collections or is it just a counter that increments with each element? I have a potentially infinite/very long sequence and started wondering if this could lead to memory issues at some point down the line.

it is open source you know..

public fun <T> Sequence<T>.count(): Int {
    var count = 0
    for (element in this) count++
    return count
}
