This is great, thank you.

I couldn't get the example in the introduction to work without adding .map!(chomp) to the pipeline:

auto sample = File("10numbers.txt")
        .byLine
        .takeExactly(10)
        .map!(chomp)
        .map!(to!double)
        .tee!((x){mean += x;})
        .array;

Without that, I got an error converting to a double (my file had '\r' after each number)

I hope this examples will be useful for students.

`parse` should works with whitespace after number:

        auto sample = File("10numbers.txt")
                .byLine
                .takeExactly(10)
                .map!(line => parse!double(line))
                .tee!((x){mean += x;})
                .array;
