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

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.

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) -- Michel Fortin michel.fortin@michelf.com http://michelf.com/ |

Looks scary, but great. :D

* There are two std.regexp and no std.regex in the package list
* std.range.advance docs mention 'drop' instead of 'advance'
* std.range.retreatN docs metnion 'advanceRight' instead of 'retreatN'

Will the final release support "osx" [sic] and "freebsd" too, or is the new Phobos going to be "Windows" and "linux" only ? > If you want to build Phobos yourself, check out the Makefile (not > linux.mak; that won't work).

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