far the two most important pieces of I/O functionality I need are:
1. Read a text file line-by-line.
foreach (line; new Lines!(char) (new File ("foobar.txt")))

yuck.
Yuck?? I find that code very elegant. How would you like it to be?
I guess something like this:
JustDoItWith("foobar.txt") {
...
}
foreach (char[] line; File("text.txt").byLine()) {
...
}
Efficient, flexible, convenient. Closes automatically the file, too,
which Tango seems doesn't.

If it closes file automatically, then why do you close it explicitly in
slurp?
Because a compiler bug prevented the destructor from functioning
correctly. The manual close does no harm now but of course should be
removed.
The code is almost the same except that "Lines" class works with any
Input Stream (memory stream, file stream, network stream, pipe, i/o
device etc).
I hope we'd be able to add such streams to Phobos too, perhaps using
your networking library for transport.
