Is this as compact as it _reasonably_ can be?

How about this?

auto uniqueWords(string filename, uint wordsize) {
    import std.algorithm, std.array, std.conv, std.functional, std.uni;

    return File(filename).byLine
        .map!(line => line.until!(not!isAlpha))
        .filter!(word => word.count == wordsize)
        .map!(word => word.to!string.toUpper)
        .array
        .sort
        .uniq;
}
