Yeah works well, as long as the code is rather simple and it occurred rather often in the training set. But I seldom use it currently (got a little bit more complex stuff going on). It's good though to find new stuff (as it often introduces a new library I haven't known yet). But actual code... I'm writing myself (tried it often, and the quality just isn't there... and I think it even got worse over the last couple of months as also studies suggest)
