Curly-infix does a little more than that. Feel free to steal its code, it is
under the MIT license.
If there are only three arguments, then it does indeed just swapped the first
two arguments. However, if there are an odd number of arguments, where the
number of arguments are three or more, and the even arguments are all
identical, then the one even argument is the front and the rest are the final
arguments. This lets you do things like this:
{a + b + c + {d * e }}

I've used several Forths and I own the book "Starting Forth".
Forth and Lisp are radically different. That said, lisp does have ways to
distinguish between actions taken while reading code, macros, and normal code.
Scheme does not have a standard way to adjust the readtable (to control what
happens while reading an expression) but common lisp does. Common Lisp also
has eval-when:

I think that controlling infix is much better if handled by the reader in lisp.
