What about the other infix libraries?

There is infix, but this works on strings, and we would like to be able to work on the AST-level. There is also infix-syntax but it's horribly complicated and terribly documented. I've tried changing that but it becomes too complicated for me.

This package is a very simple extended shunting-yard algorithm that handles n-ary functions, binary, and unary operators, and arbitrary expressions.
