This works fine for me:
import std.stdio;
import std.string;
void main(string[] args)
{
uint[string] freqs;
foreach(lines; stdin.byLine()) {
foreach(word; split(strip(lines))) {
++freqs[word.idup];
}
}
foreach(key, value; freqs){
writefln("%6u\t%s", value, key);
}
getchar();
}
Perhaps you missed an import
