infix-dollar-reader

Infix $ operator for reducing redundant paranthesis.

usage:

load package;

(asdf:load-system :infix-dollar-reader)

enable to use infix $ notation;
```
(syntax:use-syntax :infix-dollar)
```
write your forms with infix $ notation s.t. (the fixnum $ + x 10)

example:

    (fun x y $ fun2 z)

This form above would be expanded to below form.

    (fun x y (fun2 z))

And also,

    (= (+ 1 2 $ * 3 4 $ + 5 6) (+ 1 2 (* 3 4 (+ 5 6)))) ; => T

limitation:

A symbol name which has any $ characters would cause unexpected behavior.

You should not use any $ characters in a symbol name without barrier or intern from a string.

e.g.

    (syntax:use-syntax :infix-dollar)

    (defconstant foo$- 1) ; => FOO
    ;; would be parsed as (defconstant foo(- 1))

    (defconstant |FOO$-| 1) ; => FOO$- or |FOO$-|
    ;; not be parsed a #\$ as a #\( because of barrier

    (intern "FOO$-") ; => FOO$-
    ;; #\$, $-in-a-string and $-in-a-comment are not affected
