Indeed. I think __call__ has been neglected as closures have become
more widely used. In all cynicism, however, I'd argue that with
Python's very usable implementation of object-orientation, classes
with __call__ methods frequently make for clearer demonstrations of
solutions than closures do, despite requiring slightly more characters
of source code, and in contrast to the apparent fashion for using
closures for showing off more or less everything these days (despite
various pitfalls which may seem counter-intuitive to the beginner).
