I wish languages let you choose infix, postfix, or prefix freely.

Scheme does. There's a macro out there that can turn expressions into infix. Postfix is probably easier since there are no priorities. Just go through the list and push it onto a stack if it's a value or call it if it's a procedure.
(infix 3 + 5 * 2) becomes (+ 3 (* 5 2))

why? prefix is best.

Some people read and perform better in Postfix (e.g. computers, Asians)

In my opinion OOP has demonstrated that postfix/infix can be more easily read and shows transformation of data with the method chaining. You can simply read left to right.

e.g



[1,2,3].map(x => x * 2).filter(x => x > 2).forEach(print)

In contrast, prefix form.



forEach(print, filter(map([1,2,3], x => x * 2), x => x > 2))

I guess OOP also managed to fuck up notation too.
