I am finding myself often doing for loops over a subset of a list, like:

    for r in results:
        if r.numNodes != numNodes:
            continue
        # do something with r

It would be nice if the plain for loop was as flexible as list comprehensions and allowed an optional if clause, like this:

    for r in results if r.numNodes == numNodes:
        # do something with r

Has this idea come up before? Does anyone else like this idea?
