People always mention the infix operators, but really, how often do you come across them in your code? Unless you're working on something highly mathematic, it really isn't that big of a deal. Otherwise, sexprs visually are a matter of rearranging parentheses for basic function calls.

    (function1 (function2 1 2 3))

    function1(function2(1, 2, 3))

There is no difference in the way we read the first over the second.
