Thank you for the patch for windows line endings!

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)

`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;

Re: Quick Start with D: few examples and set of links.
Pipeline should be optimised (I am not sure about `tee`) by LDC,
GDC and probably DMD so all examples are generaly equal.

(.byLine(KeepTerminator.no, std.ascii.newline) and that works

because it would be one less time through the pipeline?
Learned several new things today! Thanks again!

[Hackathon] ARM Cortex-M LCD Demo
A simple demonstration using D to bare-metal program and ARM Cortex-M microcontroller. Full description with pictures and even a video can be found here: https://github.com/JinShil/stm32f42_discovery_demo/blob/master/README.md I know, random rectangles on a screen is not all that remarkable, but there's quite a bit of work that needs to be done before one can write their first pixel. * Minimal D runtime * Memory-mapped IO features * Clock and flash memory configuration * Software initialization (data and bss segments) * SPI driver to configure the external LCD controller * Internal parallel LCD controller configuration * Hardware random number generator EVERYTHING is in D. I've had this project on the back burner for a while, and the Hackathon gave me the excuse I needed to get it done. I didn't put a lot of effort into the code because I just wanted to get something working to prove some ideas I had, and show that D has some potential in this domain. I hope you find it interesting. Ask me anything. Mike

Yeah I wouldn't expect a big difference here. Even if things aren't well optimised, the various branches should be very predictable.
