Reading whitespace separated strings from stdin?

Hi guys! I had this homework assignment for data structures that
has a pretty easy solution in C++. Reading input like this...
1 2 3 # $
4 3 * ! #
20 3 / # $ #
62 # $
2 3 8 * + #
4 48 4 2 + / #
SUM # $
1 2 3 4 5 #
R #
@
...where "@" denotes the end of input is fairly simple in C++:
string token = "";
while (token != "@") {
//handle input
}
Note that having newlines doesn't matter at all; every token is
just assumed to be separated by "whitespace". However in D, I
looked around could not find a solution better than this:
foreach (line; stdin.byLine) {
foreach (token; line.split) {
//handle input
}
}
Is there any way to do this without two loops/creating an array?
"readf(" %d", &token);" wasn't cutting it either.
Thanks.
