This code:

////////////////
import std.stream;

void main ()
{
    int x;
    stdin.read(x);
}

////////////////

Produces "Error: not enough data in stream" when given some input. The same
happens if x is ubyte, byte, ushort, short, uint, ulong, long, float, double,
real, char []. It works ok if it's char or wchar. If it's wchar [], it produces
an AV. Tested with dmd 0.101/Windows XP Pro.

Assuming you ran this at the console, did you hit return without typing
anything in? As coded you have to type in 4 chars and those will fill in the
int. If you want to take string input and parse it to get an integer try
calling "scanf" instead of read. Call "read" when you have binary data.

If you want to experiment some more, try running:

import std.stream;

int main() {
int x;
stdout.writefln("type 1234 please");
stdin.read(x);
stdout.writefln("prints 49 50 51 52 right?");
stdout.writefln(x&0xFF," ",(x&0xFF00)>>8," ",
 (x&0xFF0000)>>16," ",(x&0xFF000000)>>24);
return 0;
}

and try typing in different things at the console.

I still feel there's a bug. And I'm sorry, but I think it worked before the way
I think it should (couldn't tell how long ago, though).
But thanks anyway.
