Thanks, but I meant to add that to the README or the `Commentary:`.

Also I was thinking more about the documentation on which operations are
supported.  [ IIUC you only support the four basic arithmetic
operations, with standard precedence rules, plus parentheses for
grouping, right?  ]

Also, I was wondering if you had considered implementing the parser with
the following approach:

- read the line with (read-from-string (concat "(" STRING ")"))
- massage the resulting sexp to implement the desired infix syntax.

You could even do the massaging via a macro, where

    (infix 2 + 3 * 5)
    (infix 2 + (3 * 5))
    (infix (2 + ((3) * 5)))

all macroexpand to

    (+ 2 (* 3 5))

so your syntax could be used inside code as well.
