Greetings,<br><br>I just joined here, so sorry if this has been posted before.<br><br>I'm reading TDPL and the example on page 8 doesn't compile. I'm using the latest GDC with GCC 4.4.5. I've checked the errata, but nothing for this error.<br>
<br>import std.stdio;<br>import std.string;<br><br>void main(){<br><br> size_t[char[]] dictionary;<br> foreach(line; stdin.byLine()){<br> foreach(word; splitter(strip(line))){<br> if(word in dictionary) continue;<br>
auto newID = dictionary.length;<br> dictionary[word] = newID;<br> writeln(newID, '\t', word);<br> }<br> }<br> //writeln(dictionary.length);<br>
}<br><br><br>This is the error:<br>dictionary.d:12: Error: associative arrays can only be assigned values with immutable keys, not char[]<br><br>If i use immutable keys, it works, but it defeats the purpose. So what's wrong with the code?<br>
