Two things that had been discussed on this NG that I noticed are conspicuously absent:  eager(), which converts a lazy range to an array, and range-oriented streams.  Are these still in the works?

Good questions. I forgot about eager(), and would like to think a bit more about the range-oriented streams.

I normally end up doing
writeString(text ~ "\r\n");

as the polymorphism of write is a blessing and a curse, I've had a few really annoying bugs  occur by sending the wrong type to write()...

hence writeCRLF - etc. seemed alot clearer

I wonder what fart and sniff would do. :o|

On a more (well, only slightly) serious note, the name slurp() is taken from perl (google perl slurp), and incidentally burp is around there too.

Perhaps it's a little off topic, but...

Wouldn't it be better if the language was made so that evaluating an array as a bool would yeild false when empty and true when not? This would avoid forcing the !empty double negation at many places like this one.

	while (range) range.popFront;

instead of

	while (!range.empty) range.popFront;

and

	for (auto copy = range[]; copy; copy.popFront)

instead of

	for (auto copy = range[]; !copy.empty; copy.popFront)

This is looking very impressive, will you be covering some of these concepts and idioms used in phobos in your upcoming TDPL?

This url returns a 404:

Sorry, that module is not meant to be visible yet.

Looks scary, but great. :D

Will the final release support "osx" [sic] and "freebsd" too,
or is the new Phobos going to be "Windows" and "linux" only ?

For instance, things like these look a bit hardcoded to linux:
EXTRA_MODULES_posix = $(addprefix std/c/linux/, linux socket)
