Re: Reading a file of words line by line

[mark via Digitalmars-d-learn]

I really do need a set for the next part of the program, but 
taking your code and ideas I have now reduced the function to 
this:

WordSet getWords(string filename, int wordsize) {
    WordSet words;
    File(filename).byLine
        .map!(line => line.until!(not!isAlpha))
        .filter!(word => word.count == wordsize)
        .each!(word => words[word.to!string.toUpper] = 0);
    return words;
}
This is also 4x faster than my version that used a regex -- 
thanks!

Why did you use string.count rather than string.length?
