And what about when `bar` takes several inputs? Postfix seems like an ugly hack that hyper-fixates on functions of a single argument to the detriment of everything else.

It's not like postfix replaces everything else. You can still do foo(bar, baz) where that makes the most sense.

However, experience shows that functions having one "special" argument that basically corresponds to grammatical subject in natural languages is such a common case that it makes sense for PLs to have syntactic sugar for it.

Look at the last line in the example, where I show a method being called on a tuple. Postfix syntax isn't limited to methods that take a single argument.
