Here's a challenge: try inlining the foo and bar in the call (because this is how functions are typically composed in functional programming)
You could do this with a lambda construct in Python; but this only works if the function has a single expression-statement; it doesn't work e.g. when you have a bunch of assignments inside the function you are inlining.

Sure, it's ugly but I think it's a silly challenge. Complex functions defined in the function call are un-maintainable anyway IMO.
clos = 42
def foo(x): return x + clos
def bar(y): return y * clos
higher_order(foo, bar)
What's so hard about that?
