It would be more noticeable if more operators accepted functions as their last argument rather than their first argument.

Yeah, but they don't. Lisp idiom tends to be to put the values being operated upon last, and with good reason: you want to put last the arg most likely to be a temporary. Otherwise you risk separating function calls from their args. Compare:

  (some-function
     (some-verbose-computation
       ...
       ...)
     arg2 arg3)
with:

  (some-function arg2 arg3
    (some-verbose-computation
      ...))
Since there's this major structural constraint I think any dispatch in lisp should be on the type of the last arg. (http://arclanguage.org/item?id=12646)
