...Swap your language prefs to say, arabic? ;) More seriously though, I think it depends what your background is. Maths works in prefix notation eg. f(g(x)) but I appreciate that you can hold the stack in your head easier with postfixLR.

Many people who are used to lisp would probably prefer prefix notation. non-stack or array langs have a nice tradeoff that you can look at the code without having to keep a model in your head, notably many forth users annotate their code with stack diagrams to help. Personally I'm quite taken with rebol syntax, passing a stack/array as the rightmost operand. http://blog.hostilefork.com/rebol-vs-lisp-macros/
