And I always curse Java for having to create an inner class and a method
when all I need is a simple function. :-)
I think it's Steven D'Aprano who keeps pointing out that you can always
name your tiny helper functions instead of using lambda:
def some_complex_function():
def f(x) = x + 2
some_library_that_wants_a_callback(f)
some_library_that_wants_a_callback(lambda x: x + 2)
Both calls to some_library_that_wants_a_callback run the same.
