Ctrl-Z in windows and byLine()

[Andrei Alexandrescu]

Got this from a reader:

=======================
I'm testing on Windows the code below, based on your errata changes for
p8, print 1.  It works ok if on console I enter some characters, but if I
terminate console input with ctrl-z, then there is an error exit of the
program.  So, does this code need some exception handler to handle the
immediate end of input from console?
Thanks,

void dict1_4()
{
        size_t[string] dict; // see errata use size_t
        foreach (line; stdin.byLine()){
		foreach (word; splitter(strip(line))){ // see errata required 
std.algorithm
                        if (word in dict) continue;
                        auto newID = dict.length;
                        dict[word.idup] = newID; // see errata required idup
                        writeln(newID, '\t', word);
                }
        }

}
=======================

I thought Ctrl-Z simply sends EOF to the reader, so this should work. 
What is byLine() doing wrong?


Thanks,
