I was looking at the code in samples/d2html.d and it doesn't use it but waits for a exception to get out of the while loop.

I want to read a file in chunks, but the exception doesn't seem like a good mechanism to exit the while loop and the implementation of eof() for files seems slow since it uses seeking.

InputStream is = File("test.txt");
while (is.eof())
{
is.read(buffer);
..
}

use a std.stream.BufferedFile or a std.cstream.CFile (which is buffered by the C runtime). Unbuffered file i/o will be slow. Also not I think you want while (!is.eof()).

"is" is a keyword! Cannot be used as an identifier.

hehe. good point. I totally missed that one. Plus I spelled "note" as "not". :-P
